California Rainbow Obsidian Is a Natural Wonder (Amazing Photos)

The volcanic deposits found in the Warner Mountains come in many forms. From the light weight pumice sometimes called floating rocks to the dense, glass-like obsidian, the colors and diversity are amazing. The Warner Mountains are famous for the variety of obsidian and for the four mines where the public can, with a permit, collect it.(Peppermint stripe Obsidian from Davis Creek. photo: Scott's Rock & Gem)
