Hot Spring
Another point named plainly Hot Spring, this one about two miles from Boulder City on Park Service ground in the Lake Mead recreation area. Wikipedia ties the spot to Arizona Hot Springs, also called Ringbolt, a group of three geothermal springs near Hoover Dam. The temperature on file is in the mid eighties, a warm bath at best. Access is open, and the record includes a picture. OpenStreetMap also labels it Hot Spring.
Reaching it is a hike of about two miles from the Hoover Dam-Kingman Highway. Desert floor, under eight hundred feet, bone dry, six inches of rain in a year and never snow. Averaged across the year the temperature sits in the mid seventies. Park Service land, the recreation area. No campground shows up.
Winter is the season on file, December through February. The hike is around two miles each way from the highway. Open access. No fee or camp information. The measured temperature is mild, so heat is no danger at that figure, though Wikipedia describes a cluster of springs and other vents may differ.
Wikipedia identifies this as part of Arizona Hot Springs, also known as Ringbolt Hot Springs, three geothermal springs near Hoover Dam inside the national recreation area at Lake Mead.

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.
