If you’re going to Capitol Reef National Park, you should definitely stop in at this location. It is a very short drive off of Highway 24 and the fossils are very abundant so it’s a quick stop right before the entrance to the National Park.
The fossils are unfortunately called “Devil’s Toenails”, but they are really fossil oyster shells. Most are chipped or cracked, but they are still clearly oyster shells. According to this website the shells are Oyster Gryphaea.
We also found some small pieces of chalcedony at this location and some rocks that looked like possibly some sort of fossil tube-like structure.
Marine shell fossils are very common all over Utah, so this is not a destination spot, but if one is driving through the area it’s worth a stop. We picked up plenty of fossils in less than 15 minutes.
We parked at 38.26600, -111.08029.

On a nice April day we drove out Antelope Road, east of St George, Utah, to look for marine fossils in the slope next to the road. We used this Wooster Geologists blog post as a guide.
According to that blog post, the fossils are primarily a type of brachiopod called rhynchonellids. They are crumbling out of the Virgin Limestone Member of the Moenkopi Formation. Once we found the correct area we were able to collect as many as we desired; they are incredibly abundant.
Most were loose, but some were still in the host rock. Some were solid, and some were slightly hollow inside with small quartz crystals, while others were solid quartz. See perky box photo below: the middle row left is a very tiny geode with quartz crystals, and the middle row right is solid quartz.
The largest fossils that we found were approximately 1/2 inch, but most were closer to 3/8 inch.
The road was good quality, any car could drive it.
We found the brachiopods at exactly this location: 37.04100, -113.27273

Zabriskie Station is a locality near Death Valley National Park that is said to have precious opal. It is listed in rockhounding books and a popular spot for club outings.
There is definitely precious opal here but it is very, very tiny. Most opal we found was plain, white common opal. We only found one small piece of precious opal. We didn’t stay too long because of the unseasonable warm temperatures and lack of shade.
There are probably nicer ways to spend one’s time in this area unless a small specimen of precious opal is highly desired. If you’re visiting Death Valley during the winter and want to do some rockhounding this could be a good place to go, otherwise there is plenty to see and do in the region.
We dug near 35.88638, -116.26032. The opal containing nodules are found in the hard rock layer up on the hillsides, but some could be found through surface collecting as well.
We visited during the March 2026 “superbloom” and the ground was covered in yellow and purple flowers as well as caterpillars climbing up the short flower stalks. This stop was worth it just to see the colorful flowers.

If you are traveling on highway 89 near Page, AZ the Big Water Visitor Center is worth a stop to learn about fossils that have been found in the area and its geologic history.
The address is: 20 S Revolution Way Big Water, UT 84741
This locality has been printed in rockhounding guidebooks for 40+ years. One guidebook mentions that “heavy collecting” has occurred here and pickings aren’t as abundant as they once were. Don’t believe everything you read, the petrified wood was plentiful. /
One thing that is said about the petrified wood here is that it’s not as colorful as the petrified wood closer to Holbrook. We found this to be true; most of the petrified wood we found was grey and colorless. However, it had excellent cellular replacement which makes it look convincingly life-like but not useful for lapidary purposes. One rock was so realistic that our dog, Laika, thought it was a stick and almost picked it up to chew on.
This spot is very close to the town of Joseph City and I-40 but the road is a bit rough. A vehicle with a little extra ground clearance is recommended.
The material seemed to be more abundant in the slopes of the gentle hills and washes. Keep an eye on your location as this area is a mix of private land and public BLM land.
If you’re in the area it’s probably worth checking out, but for better material DoBell’s fee dig is a better option.
We parked and explored around at 34.96979, -110.28690 but be careful to stay only on public lands.
We were driving up Arizona State Route 89 and looking for anything interesting on our drive. Small crinoid fossils at Rock Butte are mentioned in all of the Arizona guidebooks that we use. The photos in all the books did not look too promising, so our hopes were not set too high. The location is only 3 miles off State Route 89, but the road is rough and would not be drivable for cars without good ground clearance. The fossils are located in limestone that was at one point quarried. There is a large brick kiln in front of the quarry, but it’s fenced off because the kiln is in a state of disrepair and not safe to go near. There were signs designating the kiln as a protected under the Antiquities Act of 1906 as a culturally significant item, but the sign didn’t explain anything about the history of the kiln: when it was used, what it was used for and who built it.
The old kiln
The fossils are located in the quarry behind the kiln, but the rocks around the quarry had more fossils in them than the rocks in the quarry pit. The main pit was mostly light gray rocks, which were not as desirable. We had more luck with the brown-gray rocks.
The quarry area
The fossils were very numerous but also very small. We haven’t done much crinoid collecting so this stop was worth it, but for the more experienced collector this might not be a place to go out of your way to go to. We are not fossil experts so we aren’t too knowledgeable about what fossils we were looking at, but according to geologic maps the rock is Redwall Limestone and approximately 337-353 million years old.
The parking area is located at: 34.98691, -112.45406
Parowan Gap is a great place to stop to see some history in rock but it is not a spot for collecting rocks. It is located near the town of Parowan, Utah. Both sites have a walking path and parking area so they are very accessible and easy to find.
Dinosaur Tracks
The first thing to see is dinosaur footprints. Hadrosaur footprints casts, to be more specific. There are at least three different casts, all marked with a metal footprint as seen in the second photo below. The footprint casts were not quite up to our expectations, but they were a very cool piece of history to see. There a numerous sites in Utah to see dinosaur prints, perhaps this is not the most impressive of them, but it was a good introduction for us.
The parking area is located at: 37.89684, -112.95080.
One of the castingsThe casting is in the upper left of this boulderTo the north of the area
Petroglyphs
A short drive down the road from the dinosaur track site is an area filled with petroglyphs and historical graffiti. There are many informational signs explaining what you’re looking at and the history of the area. Some of the signs have literal translations of what it is believed the petroglyphs represent which aid in understanding the carvings.
We went to this area primarily to see the dinosaur footprints but were more impressed by the petroglyphs. The two sites are so near to each other and easy to access that they should both be visited.
The parking area is located at: 37.90918, -112.98405.
We’ve visited the Manresa Grotto many times. It’s located near the town of Usk, WA and is a short drive off of the highway through the area.
It’s cave-like but technically a rock shelter because it was formed by waves from Glacial Lake Clark hitting the rock shore. The cave area is 60 feet long and 25 feet high. It’s worth a visit if one is nearby and would make a good complement to a visit to the Gardner Cave to the north.
The cave is a popular site for graffiti as seen in one of the photos below. Over the years people have carved their names and the date into the cave walls which can be interesting to inspect. If approaching from the south keep an eye out for the Kalispel Tribe’s buffalo herd near the Camas Center on the east side of the river.

When we went to Fossil, Oregon to dig fossils in early May, the Oregon Paleo Lands Institute Center (OPLI) wasn’t yet open for the season. We ended up passing through Fossil again in June so we made sure to stop by after seeing on their website that they were open for the year.
The small building/museum has a nice selection of properly identified local fossils and rocks. The host on duty was very friendly, knowledgeable and eager to identify finds, of which we had none, so we would highly recommend bringing in any fossils collected from the dig site for proper identification. In addition to the rock and fossil displays, OPLI also has a small assortment of geology and local history books for sale.
There is a $2/individual and $5/family suggested donation at the OPLI. The address is 333 W 4th St, Fossil, OR 97830. More information can be found at https://www.oregonpaleolandscenter.com/.

The local history museum in Fossil, aptly named The Fossil Museum, focuses on local history, but also has a decent looking display of fossils. Unfortunately, the museum was closed when we visited so we weren’t able to go in and look around, but from what we could see looking in the windows the museum would be worth a visit. The Fossil Museum is located at 501 First St, Fossil, OR 97830.
We were highly impressed by this visitor center. It’s located in the Sheep Rock Unit of the John Day Fossil Beds National Monument. Most of the attention that is given to the John Day Fossil Beds National Monument is related to the Painted Hills Unit which is located near Mitchell, Oregon. The Sheep Rock Unit is around 45 miles east of the Painted Hills Unit.

The collection of fossils at the visitor center was very well curated, labeled and staged. The center tells the story of the John Day National Monument, thus all of the pieces in the museum were collected locally in central Oregon.
The museum is also an active fossil research facility, complete with windows and signs so that visitors can look in to see researchers working on fossils.
There’s no fee to enter the visitor center. The focus is primarily on fossils and there isn’t a whole lot of information about the area’s geology or other attractions in the national monument.
Where fossil research happens
Island in Time Trail
Although the visor center didn’t have Luckily, we brought along Oregon Rocks!, which has a feature on each of the units in the John Day National Monument. Each feature includes geological information about the area, photos and things to see
We went on the Islands in Time trail in the Blue Basin hiking area. There are a few trails at this spot, but we took the shorter one because we were short on time. The scenery was extremely impressive with sedimentary rock and paleosol formations all around you, up close. The paleosol has been altered into a blue/green color. When we there in mid-April water was flowing in the creek along the trail, but the water had so much sediment in it that it was a mint green color, which was a unique sight. There are interpretive signs along the trail but researching the area before you go will help you appreciate it even more.
The mint green creek
Mascall Overlook
This overlook is a very short drive off highway 26, near the turn onto highway 19 to go to the visitor center. The views are impressive and worth the short detour.
We set out to relocate the Big Bend Roadcut, which is rich in zeolites, as are many roadcuts in the area. The available coordinates for the cut were incorrect (but have been corrected since), but luckily we had a photo with identifying details that helped us locate the exact location. The exact location of the roadcut is 44.78267,-119.61000.
Mindat lists the site as containing analcime and gyrolite. The basalt here is very solid and hard, so all of the specimens that we could find were on the surface of the rock and low quality due to weathering. Most of what we saw were mesolite and chabazite.
We didn’t do any collecting here because this is not a safe place for multiple reasons. First, the road has very little shoulder here, mostly just a small ditch filled with broken pieces of basalt. Secondly, although the basalt containing the zeolites is very solid, the basalt above it is from a different basalt flow and is very fractured with the pieces being sharp and heavy. Some pieces were teetering on the edge of a higher ledge, looking like a few hits with hammer to the rock below could send them falling towards your head. We decided that this wasn’t how we wanted to end our trip, so we left and site untouched, but documented.

We’ve heard about the geological timeline display at Central Washington University and were passing through Ellensburg so we decided to stop in and see the displays for ourselves.
The geology department is located in Discovery Hall on CWU campus. Unfortunately it was raining when we visited so we weren’t able to fully appreciate the outside rock garden. The rock garden shows large examples of different types of rock and includes a QR code that can be used to take a self-guided tour.
Inside the building on the first floor the main attraction is the geological timeline laid out in the hallway. When applicable the epoch names are paired with information about the earth at that time and cases full of rocks from that age.
Locally collected petrified wood rounds from the Devonian epoch
Of course, no rock display in Ellensburg would be complete without a spotlight on Ellensburg blue agates. There is a display case full of interesting specimens and inclusions that can be found within them.
The specimens and information displayed are museum quality, educational and interesting, well worth a stop.
We have been wanting to go to this quarry for years, ever since seeing it mentioned in Gem Trails of Washington. In the book, a map merely points out a spot and lists “Trilobites?”.
The reason it’s taken us years to make it out here, despite it being relatively close, about 2 hours away, is that to access the quarry one must drive through a locked gate. The gate is opened by the gracious landowner, whose property is cut by the road to the quarry, only for club trips. We were invited to go along with the Northwest Paleontological Association, which has a standing trip to the quarry every September. When we visited Stonerose Fossil site, we met Greg, an fossil enthusiast who was the one who invited us and showed us around the quarry.
The specimens from this quarry that are available to reference, such as those in local museums, are unimpressive. After our top-notch trilobite finding experience in Utah at the U-Dig Trilobite Quarry, our desire to fossil hunt at the quarry lessened, but we still jumped at the chance when it came around.
Lucky we did, because the specimens that we found and that others found while we were there were much better than anything we had seen. They aren’t quite as durable and abundant as the U-Dig trilobites, but impressive nonetheless.
We only explored the lower portion of the quarry; the quarry is quite extensive. We learned that splitting rocks was not worth the time, the best tactic was to simply turn over already split rocks. We found some good specimens, although mostly lower halves and partial bodies, not many complete fossils.
In addition to the trilobite fossils, in the quarry we found pyrite, calcite, and barite druzy. Greg, our guide and expert, identified the fossil remains of excrement from a larger animal that ate trilobites.
The quarry was operated as a limestone quarry in the early 1900s, and the road up to the quarry pit passes the site of the old hammer mill. As with many historic mine sites, not much cleanup was done when operations ceased. All over the ground near the old hammer mill area were large metal balls that were used to grind the limestone, as well as other old metal relics.

After leaving Lake Wenatchee with some time to spare, we looked for rockhounding opportunities nearby. The rockhounding books recommend Icicle Creek, outside of Leavenworth, for tourmaline, beryl, and albite feldspar.
Upon leaving Leavenworth, we had a hard time looking at the roadcuts because most of the turnouts were already full of vehicles, despite it being a weekday morning. The rocks in the roadcuts that we were able to inspect were coarse grained granite with small, visible pieces of black tourmaline. The tourmaline would be attractive magnified under a microscope, but otherwise is pretty uninteresting.
The road was a little rough, but there are a few popular trailheads nearby, and we saw all types of vehicles driving it.
If you go to the location listed in the rockhounding books, they tell you to chip away at boulders to collect the tourmaline. This is definitely the way to go, but the material you’ll be collecting is likely to be uninteresting to the average rockhound.
We didn’t find any beryl, but if it’s there, it would be in pegmatite dikes in granite, and it would be opaque and impossible to remove from the matrix.
This location overall was disappointing and, in our opinion, should not be included in any general audience rockhounding books. We suspect this is one of a handful of “filler” locations included in the books.
The area is very scenic as seen in the photos below.
After bring the rocks home and inspecting them closer, we found that many of the black bits in the granite aren’t even tourmaline, but biotite crystals. Nevertheless, they look very similar to the naked eye.
One photo in a rockhounding book shows an open area with boulders. When we visited, the boulder field was extremely overgrown and not easy to walk through.
Central Oregon is an area of great abundance and variety when it comes to rockhounding. On recent trip in the area, we had some time to spare so we followed a lead for lily pad jasper. The material was said to be the same as the main lily pad jasper location, which was slightly underwhelming so we didn’t have high expectations for this spot.
Henderson Flat is part of the Crooked River National Grassland, and is about 40 minutes from Bend and from Prineville. We didn’t know anything about this particular area, but turned out it’s an OHV area. As we walked toward the lily pad jasper location that we were seeking we noticed other, colorful jasper littering the ground. The colors were varying shades of red, purple and brown and the pieces ranged from quarter sized to medium boulders, with plenty of fist sized pieces. Some pieces had some fracturing making it not ideal for cutting and working, but a lot of it was very solid and would make for nice slabs. The jasper was all over the surface of the ground, and we didn’t do any digging.
We didn’t explore the area very much, so there could be and probably are other interesting rocks around nearby. We also found some agatized wood mixed in with the jasper. The best time to explore this area would be a weekday morning because it’s a popular ORV area. The area where we collected was off the ORV trail, but dirt bikes zipping around near you would not make for nice rockhounding conditions.
The area is closed December through March. There is an abundance of great disbursed camping in the area and lots of unexplored area with unknown rocks to be found!
We stopped at this beach access point after seeing the abundance of gravel on the beach. We happened to be at the beach about an hour before low tide, perfect timing for beachcombing.
In a very short amount of time we found agates, red and green jaspers, amigdyloidal basalt and zeolites.
It was a weekend and the rain and wind were mild so there were many other people on the beach and many were looking at the rocks but we still found plenty and left plenty to be found.
Generally, during the winter and times of rough sea, sand can be stripped and rock exposed. Because of this, you might have a better selection of rocks and less competition for them in the winter. Tall waterproof boots are a great tool here as they help keep icy cold water from filling your shoes and cutting your beachcombing short. However, we did see several people walking around barefoot despite the fact that the temperature was around 45 F.
Check out the location listing for photos of zeolites that we found on the beach.

This roadcut on Highway 3 in northwest Idaho is mentioned in a few sources as having opal in the basalt and even opalized wood. The primary mention of this location is in a masters thesis from the mid 1990s.
Minerals listed as occurring in this location are pyrolusite, red opal, white opal and wood opal. We found only pyrolusite and no opal. The pyrolusite is a small, black dendritic pattern on the basalt. While interesting, this is probably not enough reason to go out of your way to check out this roadcut.
This is a great roadcut in terms of the abundance of shoulder on the sides of the road and plenty of places to safely pull over and park. The road wasn’t too busy when we were here on a weekday afternoon.
The basalt has many good examples of pillowing as well as polaganite. Another roadcut leading up to this one had some very nice sinclined basalt columns.
When we visited, the snow had completely melted but in the winter snow from plowing would make this roadcut inaccessible. This is probably not a destination but if one is driving down highway 3 in Idaho and wants to stop and admire some basalt, this would be a good place to go.

We went back to a spot that we visited last year around this time. The spot is under the bridge over the Columbia River outside of Kettle Falls. The claim is that there are blue beryl crystals in pegmatite here.
Lanny Ream’s “Gems and Minerals of Washington” describes: [the crystals] occur in a sill about 10 feet above normal water level. Presently this sill covered by the water of Lake Roosevelt. At unusual times of extremely low water, access to this pegmatite is possible.’
The day we visited Lake Roosevelt we noted that the water was as low as or lower than we’ve ever seen it, so we figured if there was a time to be able to access the pegmatite, this was it. After checking the Bureau of Reclamation’s data on Lake Roosevelt’s water levels it seems our timing was good as the water was at 1256′, the lowest it’s been in since May 2020.
Despite the low water levels, we failed to find neither pegmatite nor blue beryl crystals. Perhaps this was not an ‘unusual time of extremely low water’. However, looking into the water the rocks showed no sign of changing so we are pretty confident that we got a good, thorough look at all the rock in the area.
What we did find was a couple of pieces of granite pegmatite with very small black tourmaline. Since most of the other rock in the area wasn’t granite it seems likely that the few pieces that we saw were brought in from another area. Most of the rock was marine metasedimentary rock, not where one would find beryl.
Although we found nothing and likely there is nothing to find, we would probably go back if the water significantly drops more. It’s interesting to see the low water level and be able to look at what the riverbed looks like.
Note that this area is part of Lake Roosevelt National Recreation Area and collecting rocks is not allowed.

This is a nice spot off of Utah State Route 257. If you happen to be driving to the Sunstone Knoll or visiting the Tabernacle Hill Lava Tubes, both of which are north of this collecting area.
The road to the spot was very passable by any vehicle. We didn’t venture too far down the road so it was may get worse as you go farther. There may be claims further down the road but we saw no signage where we were.
The obsidian here that we found was black, mahogany and snowflake. The ground surface was littered with small pieces of all types but primarily plain black. The pieces on the surface were generally smaller than golf ball size but plentiful so a lot could be collected quickly with little effort. Searching the washes and gullies was more more fruitful than the open range area.
The road here goes through private property so make sure you’re on BLM land before collecting. You could spend a lot of time exploring this area and since it’s BLM land you could camp anywhere although there are no services nearby and very few people here.

We went to the area south of Dacite Mountain, near Lake Roosevelt to investigate the area at the base of the “mountain”. We have previously explored the “mountain”; more information can be found at the listing. The area near the lake is National Recreation Area and thus off limits to collecting rocks and minerals, but it’s still a very nice area and one can always look but not bring home the rocks. The lake is actually just the Columbia River and the mountain is more of a very large hill.
The bank of the lake here was sand and mud. We checked an eroding cliff for concretions which are rumored to be somewhere in Lake Roosevelt, but the cliffs were pure sand and mud. There were some interesting pieces of mudstone on the beach and near the cliff we spotted a bear print, but luckily the bear was presumably long gone from the area.Â
We then walked the lower side of Dacite Mt and found some very small tourmaline in the dacite, but nothing else of interest. This area isn’t very popular when we’ve been there, but it looked like it would make a nice swimming spot for a hot summer day.Â

This spot is mentioned in a Panorama Gem Club newsletter. The article’s author mentions coming out here around 2005. Since then, the area has significantly changed, especially as of 2015 when a wildfire came through.
Luckily, rocks are fireproof so we figured we could still maybe find something good. The Panorama Gem Club article talks about quartz crystals, smoky quartz and tourmaline. This site is right off of Boulder Creek Road, then half a mile down a dirt road. When we were here in August it was cool and raining so we didn’t risk driving the road and instead walked it.
We easily found the spot we were looking for but didn’t easily find the vein as mentioned in the newsletter, or anything of much interest. There definitely was quartz and tourmaline but nothing of great quality or quantity. On a less rainy day, it could be worth investigating the hills in the area or doing some exploratory digging.

When it’s hot, the hills southwest of Lake Chelan are always a good place to go. And they’re not crowded like the town. This was our third trip to the area in search of flourite. The last time the road was too icy to drive but this time it was clear and easily navigable by (4wd) car!
We had a lead on one spot, with GPS coordinates but as we drove as close as we could to the spot, we realized what the lines on the topo map were telling us: we were close as possible to the GPS cooridate but still 2500′ too high and no way to get down to the point of interest. UV flashlight revealed nothing notable on any rock up at the top of the hill, but we did find some great views and future campsites. The road we followed to get to this spot is called Slide Ridge Road.
See video below for a previous unsuccessful trip to this area.
Rockhounding literature suggests that 2-3 foot amethyst geodes can be found on Franson Peak. There is a 0% chance this is true, but we went out to take a look anyway. Franson Peak is primarily private timber property but the road up to the peak is public.
Assuming that there is some truth behind the claims about this area, we slowly drove up, scrutinizing roadside rocks as we drove. Around halfway up the road became too rough for our vehicle and we had to turn around. We inspected the rocks at this point and found some interesting quartz that could possibly be mistaken for agate but it was definitely not agate and not a 2-3 foot amethyst geode.
Despite not finding much, this area is still worth checking out. There is a write-up in a Panorama Gem Club newsletter of a member getting a tip and finding agates in this area. The peak south of Franson Peak, Mt Elizabeth, is primarily public land and seems like a good place to do some scouting.
We’ve been wanting to check out the Fossil Bowl in Clarkia, Idaho for a while, and when the hot temperatures finally dropped for a brief second, we headed out to Clarkia to hopefully find some nice fossil specimens!
This is fee dig, $10 per person, no time, weight, or specimen limit. Leaf, fish and small mammal fossils have been found at the Fossil Bowl. The site is also a motocross track, of the same name. The fossils were discovered when the track was originally being dug out, at that time for the purpose of snowmobiling. It’s probably best to stop by this site when there is not a motocross event going on because they can be loud and dusty. This certainly isn’t a road cut up a quiet logging road. Information on events happening at the Fossil Bowl can be found on their facebook page.
Collection of vertebrate fossils on public lands is prohibited, however this site is privately owned, so this is a rare chance to collect non-plant fossils. In our search, we didn’t find anything non-plant, but the leaf fossils were incredibly plentiful. The rock was very easy to split with a hammer and butter knife and most rocks had partial leaves or other plant material like twigs or conifer needles. We split a lot of rock and found that the best strategy was to try to cleanly separate layers in as big of rock as possible in order to maximize the chance of finding a whole specimen. We found many, many partial leaves and only one whole leaf in our entire day searching. However, the variety and quantity of the fossils was very interesting and not something that can be found anywhere else in the area.
We have very minimal fossil knowledge, but some of the fossils here are reportedly so well preserved that when the rock is split the leaf can be red or brown before turning black from oxidation. There’s a wide variety of leaf types and care must be taken to preserve the fossils after they are collected.
The site is easy to find and the large wall with the fossils is easy to spot. It’s a good idea to call ahead before making the drive out to the site because wet weather can make for poor fossil hunting conditions and a motocross event could make for an unpleasant time. Plus, you’re unlikely to have phone service at the site so better to plan ahead than potentially waste your time. We called ahead and were told to start working the fossil wall when we arrived and the person running the site would be around, but we didn’t see anyone other than some people riding dirtbikes and another person who came to search for fossils. There were no signs as to how to pay or how much to pay or any information anywhere. This may be atypical, as we’ve heard of others who have been shown where and how to find fossils and given a little more information than we got.
This is a fee dig but don’t expect much instruction or hand-holding when you come out here. Some tools are supposedly available for use, but best to bring your own. A thin butter knife or putty knife and a hammer are ideal here. There are two walls with fossil bearing rock, one is further down the road from the main wall that is more easily visible. We didn’t know this, as there is no signage, but we heard that the second wall is where the vertebrate fossils are found. We certainly found no vertebrate fossils in the first wall, so that may be true.

On a hot July day, we decided to head somewhere cool and thus went up Mount Spokane in search of the Kit Carson Mine. Multiple sources list the mine as being located between Trail 140 and Trail 110. The Kit Carson Mine is known for producing autunite, a type of uranium, which is found in a ~100 square mile area around Mount Spokane. Autunite is found in decaying granodiorite. We took Trail 110, then started tromping off trail through the huckleberry bushes and downed trees toward the mine location. However, we found no mine and no evidence of former mining activity. It is possible that we were in the right location but the dense vegetation obscured any tailing or mine detritus. We barely saw any rocks apart from the rocks on the road, which were mostly quartz and granite and did not glow under UV light.

We went out to South Baldy, north of Usk, Washington, to investigate historic reports of smoky quartz crystals near South Baldy Mountain.
As we were driving and inspecting the roadside, we noticed some obvious diggings. We went in for a closer look and found a number of dug out holes that looked like they hadn’t been worked in several years. There was a variety of material: quartz, smoky quartz, decaying granite, mica and black tourmaline. The presence of those materials generally means that quartz crystals could be present, however in our short time looking through the tailing of the holes we did not see anything resembling a crystal. There was some very clear, small pieces of quartz, but not in crystal form. With more time, it may be possible to find quartz crystals here at this dig site, or somewhere else on South Baldy.

There is a roadcut on Highway 97 in Oregon, near the town of Biggs that has historically been a source of picture jasper. In 1964 a storm washed out part of the highway here and when the road was being rebuilt, picture jasper was revealed which started the ‘Biggs Picture Jasper’ craze. The roadcut has been stripped clean…until now!
Currently, spring 2021, a highway construction project has exposed further into the cut, thus revealing Biggs picture jasper, as well as black chert. When we visited, we found a fairly large amount of high quality picture jasper. The roadcut seems a little unstable and it was clear that other rockhounds have been to this area looking for and collecting the recently exposed, highly coveted material.
In the afternoon, we found a very large, approximately 300lb boulder of picture jasper. The next day it was no longer there, meaning that someone made off with the find of the century, it only took the effort of hauling away a 300lb boulder off the side of a busy highway.

There is a roadcut off of Highway 197 right outside of The Dalles, Oregon. The roadcut has been well known since 2001. One can find yellow calcite crystal, that form in “calcite pineapples”. The roadcut also has rocks covered with a thin layer of calcite.
There is a place across from the roadcut to pull off and park, but it is at a busy road and not a destination spot or a good place for inexperienced rockhounds and kids or pets. This would be a nice quick stop when driving on I-84.

There are a couple of spots in the Rockhounding Idaho book that show garnet and staurolite cross collecting in north-central Idaho. We went to investigate them but after plotting the GPS coordinates, it’s clear that all spots are on private property. The book lists the areas as public lands, national forest, but it is definitely private property.
We didn’t spend much time investigating as it is not public property, but what we saw was garnets embedded in schist, which would be near impossible to separate out. The garnets were primarily 1/8 inch in size.
If you’re after garnets, the best spots is the Emerald Creek Garnet Area or the Fossil Bowl, both fee digs, for larger sized garnets. For free spots, the Salmon River has plentiful garnet sand, as should most of the creeks and rivers in this area.
In summary, the rocks are pretty disappointing and you have to trespass to get them.

We were driving past Rome, Oregon so we decided to stop to collect snakeskin agate since it is so unique looking and the collecting location is only a few miles off of the highway. In addition, books describe this location to also have jasper, agate and apache tears. This was a last minute addition to our trip so we hadn’t done any research or planning before we headed out to the spot.
If we had done research and planning beforehand we would have found that the GPS locations in both Oregon rockhounding guidebooks are on private property. Whether it’s okay to rockhound on this specific parcel of private property is unknown. The guidebooks clearly state that this is public lands and it clearly is not. There is public land very close to the GPS locations given in the book and there likely is agate there but it is irresponsible to send people to rockhound on private property without indicating that it is private property.
However, we were unable to make it all the way to the rock collecting spots because the road was washed out and currently is only passable by highly capable off road vehicles. The brown pin in the photo below marks where the road was impassible. There is another road that appears like it could lead to the other side of the intersection near the impassible spot, but on satellite view it’s clear that that other road no longer exists and is not a possible route in.

We were in the area so we decided to head up to the Red Marble Mine. This is a spot that we have visited previously. Some people told us that it was actively being mined and that it had been fully mined and there was no material left. This seemed doubtful so we went to check it out for ourselves. The mine did indeed look like it had been recently worked: the boulders blocking the road looked like they had been rearranged since our last visit and there were more piles of gravel in the pit. However, there is still a nearly infinite amount of material. We found some red marble with magnesite in it and some other rock with very fine pyrite on the surface.
After the Red Marble Mine we headed to the roadcut in Addy. This also is a spot that we have visited previously. Last time we drove by here we noticed that the concrete barriers had been removed so we returned to check to see what kind of work was being done at the roadcut. We found that the shoulder at the base of the roadcut had been filled in the dirt and gravel and compressed with machinery. In addition, the wall of the roadcut was covered in dirt which made inspecting the rock difficult. We found evidence of other rockhounds looking for trilobite fossils and found the rear end of a trilobite in one of their discard piles. This is the most evidence of a trilobite fossil that we’ve ever seen at this spot. The rock across the road from the roadcut was easier to search through because it wasn’t covered in dirt like the roadcut was. We found some nice sea sponge fossil specimens in that material but nothing too exciting.

Graptolites, Beryl and Concretion Rumors – April 2021
We went out following some vague reports of graptolite fossils on Kings Road. We couldn’t find Kings Road, so we took Orin-Rice Road, between the towns of Addy and Rice. We found one interesting road cut with interesting quartz, and potentially fossil-containing shale, but we were unable to find any fossils.
From there we went to the bridge in Kettle Falls, following a report of beryl crystals under the bridge when the water’s low. Found no signs of any beryl. The water was about as low as it gets, though perhaps what is considered ‘low water’ levels has changed over the years.
While we were near the Kettle Falls Campground, we decided to check if the ranger station was open to see if the concretions, as mentioned in multiple Washington rockhounding books, were on display. The ranger had never heard of them. Perhaps they were removed many years ago but the rumor remains.
This was a weekday, so we stopped in at the Stevens County Courthouse is Colville, as we’ve heard that there is a display of minerals in the building. There was indeed a very old-looking display of a great variety of minerals that have been found or mined in Stevens County. Worth a look if you’re driving through and want to take a quick break. A video and more information on the mineral display can be found here.
