Kropp Hot Spring is a hot spring off Bidwell Road in Union County, Oregon, fourteen miles or so from Union. The water is on the hot side of soaking, warm enough to feel it. Who owns the ground and whether visitors are welcome are not recorded, and no USGS site number is attached, so the temperature comes from another source.

Location

Some two hundred feet from Bidwell Road at middle elevation. Moderate snow and a couple of feet of precipitation. The nearest camping in the file is the Anthony Lake Guard Station, seventeen miles or so away, which is a long way to go for a tent site.

Winter shows as best in the record. Temperature suits a soak, but nothing is said about a pool or any improvements. Ownership and access are unknown; ask before you go. No fee listed, no chemistry on file, no land unit or designation.

Heat Below
75 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 10% 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.
