Brockman Creek Hot Spring sits on Idaho Department of Lands ground in Bonneville County, roughly thirty miles from Ammon, fifty-two feet from Brockman Road. The water is warm, mid nineties, the kind of temperature that counts as a real soak on a cold day. State land with an SRMA designation and open access. Caribou Mountain Guard Station is the camping on record, about ten miles away.
A little over six thousand feet, cold average, eight or nine feet of snow a winter, two feet of precipitation. Roadside, so the approach is trivial once you are on Brockman Road. State land managed by the Idaho Department of Lands, designated SRMA in the record. A 1976 sample gives a slightly acidic pH.
Winter leads the season ranking. Brockman Road is the approach; plowing is not documented. Caribou Mountain Guard Station is the nearest listed overnight. Water in the mid nineties is pleasant and safe. The only chemistry is from 1976. Open access under state rules. No fee recorded.
