Swim Warm Springs is a lukewarm spring in the Mt. Hood National Forest, Clackamas County, open to the public. The water is tepid, the temperature of a cool bath. It sits steps from the Whiteaway Trail at a bit over four thousand feet, with Still Creek campground under half a mile away. Mount Hood Village is the closest town listed, twenty-three miles out.

Location

This is the wet side of the Cascades. Nearly seventy inches of precipitation annually and something like two hundred inches of snow, which buries the area for a good part of the winter. The spring is on Forest Service land in the Mt. Hood National Forest, a few yards from the Whiteaway Trail. Still Creek campground is within walking distance.

The record names winter as the best season, which with two hundred inches of snow is a strange call; expect deep snow on the approach in those months. Public access is open, no fee listed. Still Creek campground is the obvious base. A water sample from 1980 shows mildly alkaline water with calcium, magnesium, sodium, sulfate and chloride; the analysis is old.

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.
