Sheepeater Hot Springs is a backcountry thermal point within Boise National Forest in Valley County, upward of forty miles from Cascade. The record calls it hot without giving a number; the only measurement is a 1980 water sample showing strongly alkaline water. The access status reads open. Reaching it is a hike of over four miles.

Location

Four miles and change separate it from the closest road, which is unnamed in the record, on national forest ground at middling elevation. This is deep snow country, close to thirteen feet a winter, and precipitation is on the wetter side.

Boundary Creek Campground is the listed camp, about eight miles away. No best months are given. With no temperature on file, you have no way of knowing from here if the water is safe to touch, so test it. Thirteen feet of snow in a season means a short window for a walk in. Nothing on file bars entry.

Heat Below
108 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 59% 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.
