Woodruff Hot Spring, nine miles from Malad City in Oneida County, is hot in name only. The reading on file from May 1972 is tepid, well below body temperature. Chemistry came back near neutral, with magnesium, sodium, calcium, sulfate and chloride present. Neither owner nor access status is recorded, so this is a spring whose legal standing you would have to sort out yourself.

Location

It lies at the roadside, about sixty yards from an unidentified road, at around forty-four hundred feet. Snow is light, about forty-four inches a winter, in a dry climate. Ownership is unlisted, as is any land unit.

Deep winter is what the record recommends. Third Creek Group Site, about eleven miles off, is the only camping the record lists. No burn risk at the measured temperature. Both readings are old, from the early seventies, and access is unrecorded, so ask around in Malad City before driving out.

Heat Below
115 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 67% 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.
