Aerial view of the ground around Hailey Hot Springs

The orange dot marks the spring, in a frame about three quarters of a mile wide.

Hailey Hot Springs is close to town, under three miles from Hailey in Blaine County, and hot, around a hundred and thirty. Democrat Gulch Road passes a few hundred feet away. Ownership and access are blank in the record, and being this near a town, that matters more than usual.

Location

Fifty-four hundred feet on the dry side of the state, with five and a half feet of snow and seventeen inches of precipitation in a year. The walk from Democrat Gulch Road is under five hundred feet. North Fork campground is almost twenty miles out, so camping is not close. Nothing on record tells you what the ground is like or who holds it.

Winter rated best, and the snow is light enough for that. Hot. Give it a careful hand before anything else. The 1988 sample gives a strongly alkaline pH and moderate dissolved solids. Access unknown; check before you go. North Fork if you need a campground, but it is a drive.

Terrain

USGS hasn't flown a detailed laser scan here yet, so this view comes from aerial photos and older elevation data.

Heat Below
92 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 34% 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.
