history

The Bannock and other Indian peoples used obsidian from the cliff for arrowheads at least 11,000 years ago . The trapper Jim Bridger was one of the first whites to mention the "glass mountain". His audience dismissed this description as a story of lies.

The formation was named by Philetus Walter Norris , the second superintendent of Yellowstone National Park between 1877 and 1882.
