Calistoga Hot Springs
Calistoga Hot Springs is the geothermal spring system in the town of Calistoga, Napa County, and the basis of a commercial resort; the town's map pin sits under half a mile away. Scalding at the source. Whether the public can get to the source itself is not on file; what is on file is a resort built over it.
Roadside in every sense, about twenty feet from the closest road, in the Napa Valley at around three hundred fifty feet. Winters are wet and snow-free, and the yearly average is mild. No land unit or public agency is attached; this is town ground and resort ground, and the nearest campground the record can find is eighteen miles away.
The season listed is midwinter. The nearest campground on file is Oak Shores Day Use Area, eighteen miles out. The resort controls the hot water, so expect to pay a resort rate; no fee figure is recorded here. Source temperature is scalding. Do not go looking for an open pool outside the resort on the strength of this page.
Wikipedia names the resort Calistoga Spa Hot Springs, formerly Calistoga Hot Sulfur Springs, and says it has run continuously as a hot spring resort since the early 1900s.
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 Calistoga Hot Springs.

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.
