How many springs

Thermal springs counted in Wyoming

NOAA’s Thermal Springs List for the United States counts 132 thermal features in Wyoming, the hottest listed at 205 F, out of 1661 across 23 states. The count is a measure of geology: Natural surface hydrothermal features (springs, pools, mud pots, mud volcanoes, geysers, fumaroles and steam vents) at 20 C (68 F) or warmer; temperatures are the maximum reported surface reading. Most sit on remote ground, on land with no public access, or too hot to approach, which is why the soaking list above is the shorter one. The hottest reading can belong to a fumarole or a steam vent rather than a pool.

Thermal Springs List for the United States, compiled by George W. Berry, Paul J. Grim and Joy A. Ikelman, NOAA Key to Geophysical Records Documentation No. 12, 1980; published by NOAA National Centers for Environmental Information (formerly the National Geophysical Data Center). Data file read September 22, 2026: the thermal springs list and its documentation. Every state’s count is on the national table.

The water

What the CDC and the Park Service say about soaking

Two hazards come up in every agency’s own words: what lives in warm water, and how hot the ground and the water can be. Both are quoted below as the agencies write them, and they apply at every site above.

Always keep your head above water in hot springs and other naturally hot (geothermal) water.

Site types above: bathhouse, developed pool and for viewing only. Fees, seasons and access change between seasons, a spring can be closed by flood, fire or repair at short notice, and a soak is at the soaker’s own risk, so the managing office is the one to check before a trip. Every state is in the national hot springs guide.
