In Washington County, Idaho, eight or nine miles out of Weiser, Old Homestead Warm Spring is a modest thing. Warm is all the record says about the heat, and no figure was ever measured. What USGS logged for flow barely counts as flow at all, and the water chemistry comes from a sample decades old. No owner is named, and public access is unknown.

Location

The nearest road is two tenths of a mile off, and the record gives it no name. Low, dry country by Idaho standards, with mild winters and very little snow, under two feet in most years. Nothing is recorded about the land around the spring or who holds it, and the elevation is low.

The record gives no best season. Mann Creek Campground is roughly nine miles off. With no measured temperature and a tiny recorded flow, expect a seep; nothing on file suggests a pool. Ownership is unrecorded, so ask before crossing any fence. The chemistry figure is fifty years old.

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 Old Homestead Warm Spring.

Heat Below
80 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 15% 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.
