Between Durango, CO, along Highway 550 and the house we rented north of the town sits an interesting rock. We drove by it a couple of times before stopping and checking it out. We found out it was Pinkerton Hot Springs. The colorful rock pile was generated as a protected area for the hot springs to release water. The water’s minerals have caused the colorful look for the rocks exterior. The temperature of the water is a sweltering 95 to 105 degrees. Be cautious if you decide to touch the water.
