Biscuit Basin Geyser, Geothermal feature in Yellowstone National Park, United States.
The geyser system includes Sapphire Pool, Jewel Geyser, and several thermal springs connected by a boardwalk within the Upper Geyser Basin.
The 1959 Hebgen Lake earthquake altered the thermal activity of Biscuit Basin, destroying the silica formations that gave the area its name.
Scientists and researchers study the thermophilic microorganisms living in the extreme temperatures of Biscuit Basin's thermal features.
Visitors access the thermal features through a 0.6-mile boardwalk loop that maintains a safe distance from the geothermal activity.
The Sapphire Pool demonstrates temperatures reaching 199 degrees Fahrenheit and contains water with a distinct Oriental blue coloration.
