Summary:

Glass Butte is a spot that probably shouldn’t be visited for rockhounding in Winter. I found that out the hard way. Due to the snow coverage, I was unable to find more than a few palm-sized chunks near some trees.

I am looking to return to this spot in the right season to try and track down some of the picturesque obsidian that comes from this location. For now, treat this page and the video below as a “how-not-to” guide to Glass Butte.

I am unsure what the standard road conditions are to access this site without snow. I was warned by locals that the obsidian is sharp enough to jeopardize your tires, so I’d recommend a vehicle with thick offroad tread if you have it available.

If I could only bring 3 tools…

Geology Pick

A geology pick is a helpful tool for prying embedded stones free from dirt and other stones.

3lb Hammer

A smaller hammer will be helpful for trimming pieces down when paired with a chisel.

Flat Chisel

A flat chisel is my preference for trimming pieces into more manageable pieces.
