Out in Malheur County, thirteen miles from Nyssa, Deer Butte Hot Spring is a low-elevation thermal spring a few degrees past where most people would want to sit for long. Who owns it, and if the public may use it, are both blank on the record. No photo has been filed either.

Location

Owyhee Lake Road gets you within about 140 feet, a roadside spot by any measure. This is dry country at under twenty-five hundred feet, with barely ten inches of rain a year and a thin dusting of snow most winters. Summers run warm. No land unit or managing agency is listed, so treat the ground as unknown until you see otherwise.

The record favors midwinter, when the air is cold enough to make hot water appealing. Light snow here rarely amounts to much. Test the water before getting in, since it runs hotter than comfortable for more than a quick dip. No campground is on file nearby, and no access status either, so a look for fences or signs is worth your time.

Heat Below
82 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 20% 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.
