Sevenmile Hole holds a set of hot springs inside Yellowstone National Park, in Gallatin County, about sixteen miles out from West Yellowstone. What comes out of the ground is far past kettle heat, hot enough to scald on contact. Nobody soaks in it. This is a thermal area you walk in to see, on National Park Service ground that is open to the public.

Location

Reaching the springs means a hike of roughly two miles from the closest road, which the record leaves unnamed. They sit at high elevation in the park interior, on land managed as national park. Winters bury the area. The record shows well over a hundred inches of snow in an average year, and the year's average temperature lands in the mid thirties. Precipitation runs moderate.

Oddly, the climate record flags December through February as the best months, which in this part of the park means snow travel, so find out what the park has open before you commit. Tower Fall Campground is the nearest camping on file, close to ten miles off. Treat the water as scalding and stay on established ground around every vent.

Heat Below
135 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 85% 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.
