Glass Mountain, a large obsidian flow at Medicine Lake Volcano.
Obsidian is a natural volcanic glass: it is a kind of igneous rock. It is produced when lava high in silica (SiO2) cools rapidly, and solidifies quickly. Because there is no crystal structure, obsidian blade edges can reach almost molecular thinness. They were used as arrowheads, and today they may be used as surgical scalpel blades.
