Gerhard Weiss sets the scene in the emerald hills of Canyon Creek, then tells the history in a few lines: Native Americans valued the springs, Robert Stuart's party camped and soaked here in September 1812, and the Pincocks built the first pool and the small resort around it.
His fact sheet is handy: 115 degree water at the source, a 96 degree big pool, a hydrojet hot pool near 105, and a 55 degree cold plunge. He notes the swim camp, the RV and tent campground, and private pool reservations outside public hours. Grand Teton is an hour away and Yellowstone two.
