Early on when I began planning this road trip I noticed Glass Buttes a little east of Newberry Volcano, a popular rockhounding site to collect unusual obsidian including mahogany obsidian and sheen obsidian where flow layers reflect back enticing shimmers of light. Digging deeper I realized Davis Creek in California's northeast corner was the site I was really thinking of, famous the world over for intoxicating rainbow obsidian where the jet black obsidian can simultaneously throw back every color of the rainbow including purples and greens if caught in the light at the right angle. There was surprisingly little information I could gather online but the quick summary is that there seemed to be a long history of private claims, a period of time when it was sent to China by the shipping container for cutting material, closure as the USFS figured out how to manage the resource, then finally in the last few years a permit system. If we could get to the USFS office in Alturas a half-hour from Davis Creek and pick up permits in person we would be free to collect two 5-gallon buckets full of the material (each) should we choose to. There are four sites where collecting is currently allowed (my quick take follows). Rainbow is probably the most accessible but does not seem to have had a large amount of material historically removed; we found none of the rainbow obsidian here, only jet black. Pink Lady has a similar sized digging area as Rainbow but we quickly found some of the namesake pink sheen obsidian in pastel hues and determined there are still large chunks to find there as well. Needles (we did not go) is known for the way the obsidian has broken into long skinny shards; it is not known for cutting material but instead for using the shards in homemade windchimes. Middle Fork Davis Creek is the clear standout with the best rainbow obsidian material of the four sites; despite a 150ft wide by 800ft long open cut indicating a vast amount of material has been removed, this was still the easiest site to fill a bucket and with the best material.
Anyway from what I could find it sounded like it could be a neat thing to try out to break up the drive home on down the back side of the Sierras and so I packed a few tools, gloves, safety glasses, a water sprayer, and buckets. I thought I had it all figured out but as we drove from Portland I noticed a major snag: the permits could only be collected in person, we wanted to collect on a Saturday, and we would be hard pressed to come off a Wizard Island shuttle on Crater Lake, drive over 3 hours, and make it to the USFS office before their 4:30pm closure on Friday (they are closed on weekends). It was probably the crux of the trip and no small feat that we managed to pull it off (more on that in the previous post). After our exhausting rally to non-stop drive multiple hours to get to the USFS office we somewhat miraculously had our permits in hand. We celebrated with a meal at the town's only old-school diner then drove on to Davis Creek. With a bit of day left we had a casual stroll around the Rainbow collecting site to try to get a feel for things. We found plenty of jet black obsidian but nothing with any hints of color that suggested this was going to be harder than I anticipated. Strangely the obsidian at all the sites was not exposed at the surface, instead requiring people to dig shallow pits to excavate chunks of the obsidian. After grabbing a few small pieces and chips we drove a mile to the Lassen Creek Campground. There were several other campers but we found a whole corner we could have to ourselves, right next to a small creek that we could wash up in. There were a few mosquitoes but for a free campsite with a picnic table and a restroom this was not a bad camp at all.
Strange loud noises in the night revealed themselves to belong to a group of free-range cattle that strolled casually through the campground in the morning. We eat breakfast and I modified my obsidian collecting plan. Since we were right next to it, I wanted to make a quick 15 minute detour to revisit the Rainbow collecting site to try to remove some of the large obsidian we spotted in fresh overhanging digging pits. I knocked out a couple pieces which were jet black with no sheens and so we drove on the surprisingly well-graded forestry roads to the Pink Lady site. Here there were a couple other people chipping rocks and digging. Our obsidian collection really occurred in three stages. In the first stage we got a feel for the diggings by walking them over, eventually finding small chips of the namesake pink sheen obsidian. Once we found an area with a decent density of pink obsidian and started to get good at realizing the strange angles to hold the rocks to get the sheen to appear, we next started collecting a bunch of fist-sized chunks into a pile. I then tried to chip corners off to provide windows into their interior, which Heather then examined for pink shines. If they passed the test, into the bucket they went. In the final and most advanced stage Heather sniffed out a good place to dig, miraculously managing to find a place between all the other places that had been previously dug and backfilled, and turned up several cantaloupe-sized chunks, each with nice pink sheen. At this point we filled up a 5 gallon bucket to its brim and I awkwardly carried it to the nearest place I could drive the car to load. This was a considerable step-up in what we found at the Rainbow site, and so my excitement grew in seeing what we could find at the Middle Fork Davis Mine site.

The Middle Fork Davis Creek mine already had four cars parked on the side of the road, clearly the place to be. This site makes you pay for your sins a bit by requiring a quarter-mile to (and more importantly from) the mine site. Everyone else we saw here were working holes in the cut face, but we started through our same collecting stages that worked so well at the previous site. Walking around we found no shortage of rainbow obsidian, only requiring us to bend over to pick it up. I got lucky finding a nice 10lb chunk of obsidian to dig out of the top of the cut that had excellent bulleye rainbow patterns. Eventually I found a good spot where someone had recently done the work of excavating a bunch of obsidian, apparently with higher standards than me. Heather and I teamed up to collect a large pile of fist-sized chunks that had not been chipped yet to reveal their interiors. We had a very high hit rate with these, with probably half revealing themselves to have readily visible rainbow patterns. There were a few good ones that I instantly regretted smashing so after a while we left some of the good ones alone. Overall it was very satisfying to chip an edge off a boring rock to reveal a color fire within. I was curious if the other folks there were finding better material than us because we seemed to fill a bucket faster and with less work than them and I was perfectly satisfied with the quality we found. With a fair bit of discomfort I carried the 70+lb bucket back towards the car, requiring frequent breaks. I opted for the direct down the hill intersection with the road that saved me about half the hike back to the car. I laid exhausted in the road while Heather retrieved the car, we loaded up, and somewhat reluctantly began our long drive across the state.

At final tally once home, we found we had collected 146lbs of obsidian- 10.5lbs from Rainbow, 65lbs from Pink Lady, and 70.5lbs from the Middle Fork Davis Mine! Overall it was a lot of fun to collect and I'm glad we rallied to make it happen. Now I need to figure out what to do with it all...
We left the Davis Creek area in the early afternoon and drove through the most sparsely populated corner of California, a desolate area of farmer fields, dry lakes, and scrubby forests that seemed to be the opposite of the dense ones we saw in Washington. Reno was thankfully easy to pass through compared to Portland or Seattle. The roadside Walker River was in anklebiting mode, a dramatic difference from the last time I saw it when it was raging at a bank-full 6000 cfs. Around 7pm we reached our destination for the night, Buckeye Creek near Bridgeport. As we pulled into the parking lot for Buckeye Hot Springs I could already tell that it might be a struggle to find dispersed camping nearby but I had a few ideas. This used to be a prize low-key hot spring compared to the more popular Travertine Hot Spring nearby, but seemingly this one too has now been insta'd and tiktok'd. As the sun got low, Heather made us quick ramen at the picnic table, then we suited up for a sunset soak. We could see the lower pool was a mad-house and there were a couple groups at the larger upper pool so we opted to soak in the smaller upper pool since we thought we had a chance of "defending" it for ourselves. This actually worked quite well and we got a peaceful soak in a perfectly hot pool and drank blood orange wheat beers as the pastels of the sunset kicked in. Before the light set too low we set off to explore our camping options, finding a ideal space set apart from other people after a few false starts.

Our last day of the trip, we awoke motivated for a morning dip in the hot springs. The population density was suitably low with only two people soaking in the riverside travertine pool and so we slipped into the prize pool with its umbrella curtain of hot dripping water. I struggled to take some photos as my phone would instantly fog. We soaked for over a half hour before hunger and the need to finish the drive set in.
Hunger drove us to stop for breakfast burritos at The Mobil, then Schat's in Bishop for Heather to load up on bread. The rest of the drive was the standard descent through the gauntlet of Adelanto, omnipresent Cajon Pass traffic, and descent into the smoggy hellscape we call home.
We managed a 15 day road trip sampling four national parks (three new-to-me), visited no fewer than six major Cascade volcanoes, and stayed some very memorable places including a fire lookout and a stunning tombolo headland with bald eagles circling overhead. I went through lava tube caves, tree cast caves, and snow caves. I got close-up to several glaciers, snuck in a few hot springs, caught up with a couple friends, and did one of the scruffiest packraft trips I have ever done. Overall we got very lucky with weather, mosquitoes, and dispersed camping. We left much to revisit or check out on a future trip (more Rainier, more North Cascades, Columbia River Gorge, more rivers, etc.), but did pretty well making the most of the long northern days. Thanks to Heather for planning all the food, use of her car, sharing the driving, and as always, the companionship.
