Biscuit Basin is a geothermal area named for the biscuit-like silica formations that once surrounded its most famous feature, Sapphire Pool. After an eruption in 1959, many of the biscuit formations at Sapphire Pool were destroyed. It's a relatively small geothermal area compared to others in the park. The entire basin can be explored via a boardwalk loop that is approximately 0.7 miles (1.1km) long.
