Sweetwater Station Warm Springs is a warm spring in Fremont County, Wyoming. The nearest town on record is Arapahoe, nearly forty miles away. Temperature is at the low edge of soaking warm. There is no land owner or public access listed, and no road name either, so the record is thin on who may visit and how.

Location

Open Wyoming range at roughly 6,600 feet, dry, with a modest snow year. Getting there means a short walk of about three hundred feet from whatever road comes closest. No campground is on file. The water chemistry was sampled in June 1990 and shows a neutral pH.

Winter months head the best list. Access is unknown; nothing on file says the public may enter, so assume you need to ask. Temperature dates to the same period as the chemistry sample, 1990, which leaves room for change. No camping listed nearby.

Heat Below
89 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 30% 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.
