Scalding. That is the first thing to know about Cabarton Hot Spring. The source runs at a hundred and sixty degrees, well past what skin can stand, and it lies a little over six miles from Cascade in Valley County, a short walk in from Cabarton Road. Who owns the ground is not on record, and there is no entry for public access either, so read this as a note on a thermal source and nothing more.

Location

Cabarton Road gets you within a tenth of a mile. From there it is on foot, though what lies between road and water is not described anywhere in the file. Elevation is moderate for this part of the state, under five thousand feet, in a valley that takes twelve feet of snow most winters and a good deal of rain across the rest of the year. French Creek campground is the closest one listed, about nine miles out.

December through February come up as the top months, which is strange in a place that gets this much snow. Water this hot will scald you. Keep off the source. No owner is attached to this ground, and permission to be on it goes unstated, so ask around town first. That pH goes back to 1979.

Heat Below
137 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 87% 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.
