A warm seep on the edge of Hines in Harney County, Millpond Hot Spring carries a bigger name than its temperature earns. The water is tepid, bath-cool, nowhere near hot despite what the map label says. It is recorded as a USGS thermal site and sits about a mile from town. Who owns the ground, and if the public may walk onto it, is not on file.

Location

Hines sits in Oregon's high desert basin country, over four thousand feet up with dry air and cold winters. The spring is a roadside point, roughly a hundred yards from the nearest road, so there is no approach to speak of. Snow is moderate here and rain is scarce, a little over a foot a year. No road name or land manager is listed for it.

Winter months rank best in the record. With water this cool, timing hardly changes the soak. Both the landowner and the access status are blank; confirm them before walking in. Idlewild is the closest campground listed, nearly nineteen miles away. No fee is recorded.

Heat Below
74 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 9% 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.
