An unnamed spring in Tooele County about eight miles out of Grantsville, with water that is barely warm, cool enough that most people would not call it a hot spring at all. It has no USGS site number, no recorded owner and no access status. What the record does give is a location a few hundred feet from a road.

Location

This is roadside ground on a low valley floor, a couple of hundred feet from an unnamed road. Winters drop a couple of feet of snow and the climate is moderately dry, with about fifteen inches of precipitation through the year. No land manager is on file, and no unit or designation either, so the record is silent on whose ground this is.

The record leans toward winter visits. Lower Narrows Campground is close to fifteen miles away. With no water sample, no temperature date and no access information, this one needs a phone call or a map check before it is worth the drive. The water would feel cool to most bathers.

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 this spring.

Heat Below
113 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 63% 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.
