Glass Buttes obsidian again: LAPC

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.

A gallery of Glass Buttes obsidian

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.

Rock Garden windows: Monday Window

Here is a close up of rock garden windows in a model of a building at Petersen Rock Garden and Museum in Redmond, Oregon. The walls are covered with black and mahogany obsidian.

The windows shown above are on this building. It is impressive!

The row of colorful lawn chairs in front of it adds a nice touch.

Special somethings around the house: LAPC

This post includes photos of smaller-sized special somethings collected over the years.

Special somethings discovered

The first photo shows a radiator cap from a 1928 Pontiac. We found it buried in the forest where we used to live. The Indian brave sculpture is so detailed!

The next photo shows a picture of my favorite salt & pepper shakers. This pair was found in an antique store in Snohomish, Washington. I’m not sure what year these were made, but they look like Depression-era glassware.

The next photo shows a piece of black obsidian. I found this piece at Glass Buttes, about an hour east of Bend, Oregon. This rock has radiating curves that developed as it cooled thousands of years ago.

Many shades of obsidian: Weekend Challenge

There are many shades of obsidian in nature. The Weekend Challenge from GC and SueW, and their monthly color challenge for June, is the color Obsidian.

By coincidence, I was out in the yard yesterday morning rearranging some of the obsidian I’ve collected at nearby Glass Buttes. Here in Bend, Oregon, we recently had a huge storm with high winds, rain, and hail. My rocks all had a nice bath. 😉

Here are few portraits of obsidian rocks in my garden.

Obsidian Up close & personal

I enjoy visiting Glass Buttes in Central Oregon to collect obsidian. Did you know there are over 24 kinds found there? Here are photos of obsidian up close. The stones are beautiful in color, but also in form.

I went on a field trip recently to one of my favorite places–Glass Buttes. Obsidian is everywhere you look! It’s like being a kid in a candy store. In fact in one of my previous posts, Glass Butte Dragonglass, I show a picture of some obsidian I have collected displayed in a candy bowl.

Glass Buttes – Rockhounding and habitat

Located about halfway between the towns of Bend and Burns in eastern Oregon, this site is a rockhounder’s paradise. You can dig and crack open obsidian with a rock hammer, but you really don’t need to because it’s all over the surface.  The Bureau of Land Management oversees most of this site. Individuals may collect up to 250 pounds of obsidian per year.

Glass Buttes Dragonglass AKA Obsidian

Dragonglass collage

Game of Thrones fans may know what dragonglass is but the rest of you may be going, “Huh?” The rock plays an important role in the story.  Most people know it by the name obsidian. Like glass, obsidian fractures into pieces with sharp edges. It can be found in a wide variety of colors.

Obsidian from my yard

Obsidian forms when lava from a volcano cools rapidly with minimal crystal growth. Volcanic activity in Central Oregon is recent, in geological terms, so obsidian is fairly common in some areas. Lava flows covered hundreds of acres in this region. I have found obsidian in my yard between the sagebrush and bunchgrass. Isn’t this a cool piece?
