Glass Butte Recreational Rockhound Area
Public
Lake County
Glass Buttes is a rhyolite and obsidian complex with an unusually broad suite of gem-quality obsidian, including mahogany, rainbow, gold sheen, silver sheen, midnight lace, and other varieties documented by Oregon State University. The BLM-managed setting makes it one of Oregon's strongest public-land examples of volcanic glass collecting, with ordinary rockhounding rules still requiring attention to claims and local restrictions.
