Warm Mineral Spring
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Warm Mineral Spring is a roadside warm spring in the Whitman National Forest, Union County, about 25 miles from La Grande. The water comes out warm, well under body temperature, so this is a dip on a hot day more than a soak. Access is open. It sits a hundred yards or so off a forest development road, which makes it easy to reach once the road is clear.
National Forest Development Road 5160 passes within a few hundred feet. Forest Service land, a bit over 4,300 feet up, and this is wet country by eastern Oregon standards: over thirty inches of precipitation a year and something like nine and a half feet of snow over a winter. The nearest camping on file is Anthony Lake, roughly thirteen miles away.
The record rates December through February as best months, yet with the snowfall here a forest road is unlikely to be drivable then, so confirm the road status with the Forest Service before relying on it. Anthony Lake is the campground on file. No fee and no water chemistry appear on the record. The temperature is warm at best; do not expect a hot soak.

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.
