## About Warfield Hot Spring

Warfield Hot Spring is the name the survey uses; Wikipedia calls the same place Frenchman's Hot Springs or Frenchman's Bend. It lies along Warm Springs Creek outside Ketchum in Blaine County, with source water hot enough that it needs cooling before anyone sits in it. No owner appears in the record, though Wikipedia places it within the Sawtooth National Forest. No public access status is on file.

You can pull up almost on top of it, roughly a hundred feet off an unnamed road. Above six thousand feet, so winter means snow, over a hundred inches in an average year, with the climate dry the rest of the time. Ketchum is six and a half miles away by the record and eleven by the Wikipedia entry.

Wikipedia describes Frenchman's Hot Springs, also known as Frenchman's Bend or Warfield Hot Springs, as three wide, shallow pools along Warm Springs Creek in the Sawtooth National Forest, walled with rock and floored with sand and gravel.

The coldest months of the year are the ones recommended. Easley Campground is about ten miles off. The source is hot, and the pools Wikipedia describes will vary; test before settling in. Access is not recorded, so confirm locally. The temperature was measured in May 1988.
