Granite Falls Hot Springs is a hot spring in Teton National Forest, about eighteen miles from Jackson, Wyoming, in Teton County. The water comes out at 112 degrees, hot enough that most people want it cooler before sitting in it. The Forest Service manages the land and access is open. This site also lists Granite Hot Spring nearby, and Wikipedia describes them as one place.

Location

The closest road, name not recorded, is only a tenth of a mile away. Sitting near 6,900 feet, the place gets severe winters. Over thirteen feet of snow. Precipitation for the year runs a bit past two and a half feet. This is national forest land, and Hoback Guard Station, ten miles or so out, is the nearest camping listed.

Hot enough to need care: ease in and move if it is too much. The record lists winter as the best season; with thirteen feet of snow that will mean whatever the Forest Service keeps open. Access is open, no fee on record here. There is no water chemistry in this record; the neighboring Granite Hot Spring record carries a 2019 sample.

History of Granite Falls Hot Springs

According to Wikipedia, early settlers dug a pool at Granite Hot Springs to catch the water, and the site is kept up by the Forest Service. The USGS holds a separate station number for this point.

Heat Below
86 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 25% 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.
