New Biltmore Hot Springs, which OpenStreetMap labels plainly as Biltmore Hot Springs, lies off Ziegler Hot Springs Road in Beaverhead County, nineteen miles from Dillon. Hot water, hotter than most people could sit in as it comes from the ground. Ownership and public access are not on record. A 1978 USGS sample found the water slightly acidic and carrying iron.

Location

A roadside spring, a couple hundred feet from Ziegler Hot Springs Road, down in a dry valley in the southwest corner of Montana. Winters are light on snow and rain is scarce. Neither land unit nor designation is listed.

Hot water: check it with a hand before committing a body. Hells Canyon Guard Station, sixteen miles off, is the camp listed. Midwinter carries the best rating, and light snow makes that plausible. Nobody has recorded if the public may visit, so ask first.

Heat Below
89 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 29% 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.
