Sol Duc Hot Springs
Sol Duc Hot Springs is a hot spring inside Olympic National Park, and the campground on record is the Sol Duc Hot Springs Resort campground, which says something about what kind of place this is. The source water runs hot, beyond soaking temperature. Access is open, the Park Service holds the land, and the road is right there.
Eighty-odd feet from the road, so roadside by any measure. Elevation is around sixteen hundred feet in the Olympic National Park interior. Wet: the climate record shows eighty-some inches of precipitation plus a snow total above a hundred inches. The water sample on file, from 1967, shows strongly alkaline water with moderate dissolved solids.
The resort campground is a third of a mile away. Winter comes up top on record, and snowfall is significant, so find out if the park road is open before you go. The source can burn; whatever pools exist, test before entering. Fee not on record.
The water chemistry on file goes back to a sample from October 1967. USGS holds a site number, and OpenStreetMap uses the same name.
USGS hasn't flown a detailed laser scan here yet, so this view comes from aerial photos and older elevation data.

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.
