Upson County, Georgia, holds Thundering Spring, nine or ten miles from Hannahs Mill. The name promises more than the temperature delivers. Water on file is mid seventies, warm in the way a lake is warm in June. It lies a few hundred feet off the nearest road, a short walk. Ownership and public access do not appear in the record.

Location

Under seven hundred feet, mild average temperatures, a wet year, an inch of snow if that. Reaching it means a few hundred feet on foot from the road, across land whose owner goes unnamed. There is a USGS site number and nothing else official attached, no land unit, no water sample.

Cool season first, December through February. Camping and fees are both blank in the record. The nearest road is unnamed and access status is unknown. Nobody needs a safety warning for water in the seventies, though a temperature this low means a dip at most.

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 Thundering Spring.

Heat Below
55 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 0% 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.
