OpenStreetMap knows this one as Three Forks Hot Spring; the survey record leaves it unnamed. It is a warm spring on BLM ground in Owyhee County, thirty-one miles from Murphy, with a recorded temperature in the mid nineties, warm enough to sit in without being hot. Access is open. Getting there takes a hike of about a mile and a half from Skull Creek Road.

Location

Skull Creek Road is where you leave the car. From there it's a mile and six tenths of walking. The ground belongs to the Bureau of Land Management, Vale Malheur Field Office. Elevation is a hair under four thousand feet, high desert and dry. Snow in a normal winter runs about two and a half feet. Camping on record is North Fork Campground, roughly eleven miles off.

Winter carries the best rating, December through February, though snow will be a factor in the approach on a hike this long. Access is open, no fee listed. Camp at North Fork, eleven miles out. No water chemistry has been filed. Mid-nineties water feels warm in cold weather and mild in summer heat.

History of This Spring

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 19% 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.
