Out in Lincoln County, nearly fifty miles from Pioche, Moon River Spring comes up warm on Bureau of Land Management ground that the record lists as open to the public. The water is soaking warm, comfortable for a long sit. It is a long way from anything.

Location

The spring is a roadside stop inside the Bristlecone Field Office area, under a hundred feet from the track. Which track is not on record. Elevation is middling for Nevada, high desert a bit over five thousand feet, and this is a dry corner of the state. Snow comes lightly, around a foot and a half in a typical winter, and the whole year's precipitation is about seven inches.

Winter rates best here, December into February. You can drive nearly to the water. The BLM lists it as open, with no fee on file. There is a USGS site record for the spring, so the temperature comes from a real measurement, though the date of that reading is not noted. No campground is on file anywhere close, and Pioche is the nearest town of any kind.

Heat Below
95 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 40% 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.
