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.

Iron and magnesium give the obsidian a dark green to black color.Obsidian has several varieties.hough obsidian is usually dark in color similar to mafic rocks such as basalt, obsidian's composition is extremely felsic.
