Three miles from Cascade in Valley County, Idaho, Belvidere Hot Spring is a short walk off Cabarton Road. The source runs hot, a bit past the soaking range, and the water leans strongly alkaline. No landowner is recorded, and the access status is blank. A photo is on file for this one.

Location

A tenth-mile off Cabarton Road, at around forty-eight hundred feet. Snowfall is heavy, nearly thirteen feet in a normal year, and the climate is on the wet side, averaging in the mid forties. No land unit listed. French Creek Campground is five or six miles away. Having a named road helps with finding it.

Best months listed: December through February, with that snow, so plan accordingly. The walk is short. At the source it is hot enough to want cooling, and nothing on file mentions a pool. Public access is not on record. Chemistry is from 1979 and has not been resampled since.

Heat Below
135 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 86% 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.
