Mormon Reservoir Warm Spring is a warm spring in Camas County, Idaho, between six and seven miles from Fairfield. The record is thin. It is classed as warm without a measured temperature, so there is no number to go on, and calling it a soak would be a guess. Owner and access are unrecorded, and no water chemistry was ever sampled as far as the record shows.

Location
27 miles from Glenns Ferry, ID

Four tenths of a mile of walking gets you there, off a road the record leaves nameless. Nobody wrote down the elevation. The land owner and land unit are blank too. Around Fairfield the climate stays cool and fairly dry, with something near fifty inches of snow over a winter. After the county and the distance into town, the record quits.

No best season is on record. Bowns Campground is the only camping listed, and it is a long way off, around twenty-four miles. No temperature means no heat warning either way. Treat everything about this spring as unconfirmed and learn who holds the ground before heading out.

Heat Below
130 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 80% 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.
