Weatherby Hot Spring
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Weatherby Hot Spring comes out hot, low teens above a hundred, in Boise National Forest country about 25 miles from Idaho City in Boise County. Middle Fork Road is roughly 1,500 feet away. Access is open. The temperature sits right at the edge between a hot soak and too hot. The USGS carries it as a site without a water sample.
Around 4,400 feet. Snow is heavy, about 150 inches a year. Precipitation is thirty-odd inches and temperatures average mid forties. Forest Service land, plain National Forest designation, fee not recorded. The road is Middle Fork Road and the spring is a short walk in from it, with nothing on file about the condition of either.
December through February are listed as best months, which with that much snow means a winter approach over snow. Deer Park Cabin is the closest overnight option on record, about eight miles away. No chemistry is recorded. A bit above 110 the water can scald with prolonged contact, so test it first.
Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Weatherby Hot Spring.

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.
