## About Eldorado Springs

A warm spring in Boulder County, six or seven miles out from Boulder. Tepid is the honest word for it, something you notice with a hand and little else. The USGS lists it among thermal sites, and a chemistry sample from 1976 came back low in dissolved solids. No one has put an owner to the ground, and nothing says whether the public can reach it.

Chesebro Way runs within a few steps of the spring, so the approach is roadside. Elevation is foothills height. Winters here bring real snow, around five feet in a typical season, and the rest of the year leans dry. No land owner appears in the record, and no designation either, which leaves the question of who controls the spring open.

The calendar favors December through February, when the contrast with cold air is sharpest. Reaching it is easy, yet public access is unrecorded, so check ownership before you go. Kelly Dahl is the campground on file, roughly a dozen miles away. The mineral reading dates to 1976 and should be treated as a snapshot.
