Biscuit Basin Geyser, Geothermal feature in Yellowstone National Park, United States.

Biscuit Basin is a geothermal area in Yellowstone National Park featuring hot springs, colored pools, and geysers. The features are connected by a wooden boardwalk that keeps visitors safely near these boiling and steaming natural phenomena.

The area was named for its chalk-white silica formations that resembled biscuits, but a major earthquake in 1959 fundamentally changed its thermal activity. This event destroyed many of the characteristic structures and permanently reshaped the landscape.

The colorful pools and steaming features draw visitors who gather to watch the mineral deposits and bubbling waters up close. Local guides and tourists alike walk the boardwalk together, finding common ground in their wonder at these visible natural forces.

Access is through a roughly 1-kilometer walk with clear views of all thermal features. Sturdy footwear and caution are important since the path passes near hot water and steam vents.

Biscuit Basin Geyser sits at 2,221 metres in a valley in Teton County, Wyoming, about 1.6 kilometres from Jewel Geyser, the higher landmark to its northeast. The surrounding slopes are mostly mountain terrain, with flatter ground to the east, and the area is classed as boreal climate, averaging 0 °C.
