Sulphur Spring
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Sulphur Spring sits off Pumpernickel Valley Road about 21 miles from Winnemucca in Humboldt County, on public land the BLM runs from its Humboldt River Field Office. The record classes it as hot but carries no actual temperature reading, so do not count on a soak. Access is open. The listing lacks a USGS site number. It lacks a second name and a photo too.
Roadside, under a hundred feet from Pumpernickel Valley Road. Open BLM land with the standard public designation. Snowfall is under two feet in a typical year and precipitation around ten inches. Elevation is moderate.
No best months are on file. Access is open and roadside. With no temperature on record, expect to find out on arrival what the water is like. There is no chemistry on file, and neither fee nor campground is listed. No photograph either.
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 Sulphur Spring.

That's about twice the US average of 65. It's higher than at 73% 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.
