## About Elkhorn Warm Spring

Elkhorn Warm Spring is barely warm, low seventies, on Bureau of Land Management ground in Madison County about twelve miles from Rexburg. The record marks it open and puts it a tenth-mile walk from the road. The water is nowhere near bath temperature, and nobody has sampled its chemistry, so the reading on the thermometer is the whole of what is known about the water. A photo is on file.

BLM public land under the Upper Snake Field Office, at about fifty-three hundred feet. Winters bring under four feet of snow, a fairly dry place overall at eighteen inches. The walk from the road is short, road unnamed. Kelly Island Campground is under four miles off per the record. Nothing describes the ground or the water at the spring.

The record favors winter, and with modest snow that is reachable. Open access on BLM land. Kelly Island for camping, a few miles. The temperature is the one hard fact here, and it rules out a soak, so go for the place and the walk and expect cool water.
