## About Heise Hot Springs

East of Rexburg in Madison County, Idaho, a little over thirteen miles from town, Heise Hot Springs is a hot source whose temperature on record sits past comfortable soaking and into the range where you would want it cooled first. Who owns the land and what the public may do there are both missing from the record, which matters for a spring this close to a named road and a campground.

East Heise Road comes within a couple hundred feet, so this is roadside in any practical sense. The ground here is lower and drier than the mountain springs farther west in Idaho. Winter snow is moderate, under four feet most years, and total precipitation is on the light side. No land unit or designation is on file, so the surroundings are unrecorded beyond the road name and the county.

The record favors the winter months. Kelly Island Campground is about two miles off. Going by the temperature on file, test the water with a hand before you step in. Nothing in the record says the source is open to the public or who owns it, and the only chemistry sample dates to 1977, so confirm both before planning a trip.
