Ray Lunt Spring is a barely warm spring a couple of miles from Mona in Juab County, Utah. It carries a person's name and a single USGS water sample from 1965. The water is cool enough that soaking is off the table. Who owns the ground, and if visitors are allowed, are both blank on the record.

Location

Short walk territory, a third of a mile in from a road nobody has named on record. The valley sits a bit under five thousand feet and picks up about four feet of snow across the winter. Nothing is listed for land unit or designation, and no manager appears either.

Winter is listed, though there is little reason to go then for the water itself given how cool it runs. Bear Canyon campground is eight miles off. The sample is sixty years old and shows fairly mineral water. Access is unrecorded.

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 Ray Lunt Spring.

Heat Below
139 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 88% 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.
