Sheepeater Cliffs on the Grand Loop Road, south of Mammoth Hot Springs is named after the Shoshone people, also known as the Tukudika or 'Sheepeaters,' who once lived here. The cliffs are composed of columnar basalt, formed from lava flows about 500,000 years ago. The hexagonal columns were created as the lava cooled and contracted, resulting in the distinctive jointing patterns seen today. The site provides insights into the history and lifestyle of the native Shoshone people who utilised the area for hunting bighorn sheep and other resources.
