A few weeks ago, we drove about an hour east of our home in Bend to collect Glass Buttes obsidian again. Sometimes it’s easy to forget about going on adventures close to home.
I wrote about going on a field trip to Glass Buttes on my blog in 2018. In that post, I explained some of the geology behind this site. I’m lucky it’s just a short drive away.
On the recent trip there, we drove to one our favorite spots to collect obsidian. Yes, there are maps showing where certain types can be collected. However, at Glass Buttes you don’t have to go far to find obsidian. It’s everywhere!
If you go here, be aware that it’s easy to drive right past the entrance near mile marker 78 on Highway 20 since it’s unmarked. Drive south of Highway 20 on the dirt road, and drive a mile and a half or so. You can continue straight or turn to the left or right. On some of the side roads, 4WD high-clearance vehicles are recommended, but you can find lots of obsidian on both sides of the main road.
There is a new interpretive sign a little ways in on the road to the buttes. You can stop here to read about the importance of this site to native peoples and a few facts about the geology, recreational opportunities, and the danger of wildfires.
On this trip, I took my drone to photograph the landscape. At first glance, it may appear to be “drive by” country. However, looks can be deceiving.
If you go in the spring and summer months, you’ll see beautiful wildflowers like the lupine in the photo below. You’ll also see birds flitting between the sagebrush. On our trip, the air was filled with the songs of the shrubsteppe-dependent songbirds I studied for my graduate thesis. I heard or saw Brewer’s Sparrows, Sagebrush Sparrows, and Sage Thrashers.
It can get pretty hot here, so if you bring your dogs, don’t forget to bring them water. Bring plenty for yourself as well.

Here are a few of the pieces of obsidian I collected that day. There are at least 20 different kinds of obsidian at Glass Buttes.







What do I do with all the obsidian I’ve collected? I display pieces in the landscaped areas outside and feature some of my favorite pieces on shelves inside.

What a fun visit this must be! The photos are great.
Thanks, Egidio! It’s nice to be able to find them so easily. No rock hammer required.
It is a fabulous rock. I am surprised that people can pick it up and remove it from the environment
Yes, it is! You can take 25 pounds a day/ 250 pounds per year there.
Thanks for the info. I hope the place doesn’t get decimated by pickers
The more rare types get picked out, but it’s like a mountain made of obsidian. Tons of it. 🙂
That really is amazing then
Great photos. Incredible that it is there for the taking.
Thanks! Yes, it’s open to all. 😁
Ah, found you tonight in the spam section…a lovely adventure! I would have loved to go there treasure hunting. My grandchildren would have loved it too – an adventure for all ages!
Thanks, Ann-Christine! 🙂 I’ve had stuff lost in the spam folder as well.
