Squaw Hot Springs is in Franklin County, three miles from Preston. The water is scalding, well above anything you could sit in, and very salty, with dissolved solids in the thousands on the 1972 sample. Flow was measured at three cubic feet per second, a good deal of water. Owner unknown; access unknown.

Location

North 2200 West passes a hundred and fifty yards or so away, a short walk. Valley floor at middling elevation, with a cool average, snowfall near four feet and a dry year. Nothing in the record says who manages the ground between the road and the water.

Camping on file means Third Creek Group Site, eleven miles off. Best months are winter, January at the top. Do not touch the source water; it will burn. No owner is recorded, so confirm access before going. The chemistry is from 1972, and the salt load then was extreme. With the flow that high and the water that hot, keep well back from wherever it emerges.

Heat Below
141 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 89% 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.
