Biscuit Basin is "named for the unusual biscuit-like deposits that used to surround Sapphire Pool ... Biscuit Basin is traversed by an easy 0.6-mile (1-km) lollipop loop boardwalk trail, which leads past many fascinating hydrothermal features, such as Sapphire Pool, Avoca Spring, and Jewel Geyser." Hot spring colors range from green to blue to turquoise, with orange and brown veins of bacterial mats surrounding and leading away from the pools.
