Unnamed Thermal Spring
Harney County's Malheur National Wildlife Refuge holds this unnamed thermal point, about 22 miles from Hines. Tepid water, right around seventy degrees. Access is restricted. Since this is a wildlife refuge, its own rules decide if you can get to it at all. The USGS lists it under a site number of its own.
The nearest road is South Harney Lake Lane, and the spring is a two and a half mile hike from it across refuge land managed by the U.S. Fish and Wildlife Service. The elevation is around forty-one hundred feet. Snow is moderate, under two feet most winters, and the year is dry at about a foot of precipitation.
Winter months are flagged on file. Access is listed as restricted, so check with the refuge before setting out and expect closures. The water is too cool for soaking anyway. No campground or fee is recorded. The hike is long enough to plan for.
