Colorado: Have any of Y’all been out to Hot Sulphur Springs to relax in the mineral baths? What a fantastic place! These baths were originally discoverd by the Ute Indians who believed that they held natural healing powers. Then they were acquired by William Byers, of Byers Peak fame, and the pools were turned into a resort that has been operating for the last 140 years. There are 22 pools varying in temperature from 95F to 112F.
