Geyser: Not a Soaking Spring

Mud Geysers is a geyser, not a traditional hot spring. These geothermal features can be extremely dangerous. Boiling water, toxic gases, and unstable ground are common hazards. Do not attempt to soak.

Mud Geysers is a thermal feature on the Gallatin County side of Yellowstone, a short walk in from Grand Loop Road, marked hot on the record without a measured temperature. The Park Service holds the land and lets people in. West Yellowstone lies about sixteen miles off. With no reading on file, there is nothing here to call soakable.

Location

Three tenths of a mile separates the Grand Loop Road from this spot, which sits at close to seventy-nine hundred feet. Snowfall runs past twelve feet in an average year, with an annual mean of thirty-four and middling precipitation. The land is designated national park.

No best months are on record. With the road close, the season is whatever the park keeps open, so ask. Tower Fall Campground, the one campground on record, sits about nineteen miles away. No temperature means no assumption of safety; treat the ground and water as hot. Free, by the record, and open.

Heat Below
112 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 63% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.

Mud Geysers sits at 7,870 feet above sea level, way above the mile-high mark. You may not feel the altitude strongly, but hot water still dehydrates you faster at elevation. UV is about 31% stronger than at sea level, so bring sunscreen and drink more water than you normally would.
