Ninemile Springs
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Ninemile Springs in Humboldt County is a warm spring, tepid by hot spring standards, about 58 miles from Winnemucca. The water is cooler than body heat. No landowner or access status is on file. What is on file is a water sample from 1959 showing low dissolved solids, not much mineral in it at all.
Ninemile Road runs within a tenth of a mile, so there's barely any walking. The elevation is low for northern Nevada, under 4,500 feet, and the year is dry, ten inches of precipitation with around two feet of snow in winter. Nothing on the record describes the pool or the ground around it.
The record rates the winter months best. Getting there is easy once you are on Ninemile Road. At this temperature the water will feel cool in winter air, which is worth weighing against the season rating. No campground listed. Access and ownership are unknown, so look into that first. The chemistry on file is from the Eisenhower years and has not been rechecked.
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 Ninemile Springs.

That's about 1½ times the US average of 65. It's higher than at 47% 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.
