Unnamed Thermal Spring

Under nine miles from Homedale and barely a hundred yards off the road, this unnamed thermal point in Owyhee County is about as easy to reach as BLM springs get. The catch is that the record gives no temperature. It is flagged hot, nothing more. Access is open and the ground is public. A 1991 water sample is on file and it came back strongly alkaline.

Location

The nearest road is unnamed on the record but the spring is only a few hundred feet from it. Bureau of Land Management ground, managed from the Vale Malheur office. Low desert elevation, around 2,700 feet. Dry, with a couple of feet of snow over a typical winter. Slocum Creek Campground is the closest camping listed, roughly a dozen miles away.

There are no best months on file. Open access, no fee recorded. Camp at Slocum Creek if you need a site, about twelve miles off. The analysis from October 1991 lists sodium, calcium, magnesium, chloride and sulfate at a pH well above nine, so this is alkaline water on paper. Without a temperature on record, do not count on a soak.

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
78 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 13% 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.
