Another Hot Spring in Lake Mead NRA, Clark County, this one thirteen miles or so out of Boulder City and a little warmer than its neighbor, low eighties. OpenStreetMap uses the same plain name. A 2008 sample found it heavy in dissolved solids and the analysis picked up iron. The Park Service manages it and access is open, reached by a hike of about 1.5 miles.

Location

Low desert, a little over eight hundred feet, inside the Lake Mead recreation area. The road the record measures from is unnamed. Zero snow in an average winter. Rain comes to about five inches a year and the yearly average is in the low seventies, so the cool months are short. The walk and the spring itself are not described.

December through February is the window on record. Plan the hike for early or late in the day outside those months. Open access on National Park Service ground, no fee noted, no campground named. The 2008 chemistry is not old as these things go. Low-eighties water will not hurt anyone.

Terrain

Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Hot Spring.

Heat Below
106 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 55% 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.
