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.

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

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 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?
