Biscuit Basin is an extraordinary geothermal area in Yellowstone National Park, Wyoming, USA. Named after the biscuit-like deposits that were once found around Sapphire Pool, Biscuit Basin is a wonderland of hot springs, geysers, and vibrant colors that captivate its visitors.


Long before it was known as Biscuit Basin, the area was a sacred site to Native Americans. The first written records of the area were made by explorers in the late 1800s, who were awed by the basin’s colorful hot springs and powerful geysers. The name ‘Biscuit Basin’ was given due to the unique biscuit-like formations around the Sapphire Pool. These formations, unfortunately, were destroyed in the 1959 Hebgen Lake earthquake.
