Obsidian Cliff. Obsidian Cliff, designated a National Historic Landmark in 1996, is located on the Grand Loop Road between Mammoth and Norris. Obsidian is found in volcanic areas where the magma is rich in silica and lava has cooled without forming crystals, creating a black glass that can be honed to an exceptionally thin edge.
Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure.It is an amorphous material known as a  mineraloid ..The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo on right). Obsidian is usually an extrusive rock-one that solidifies above Earth's surface.However, it can form in a variety of cooling environments: Black is the most common color of obsidian.he first use of obsidian by people probably occurred when a sharp piece of obsidian was used as a cutting tool.
