About Pagosa Hot Springs
World’s Deepest Geothermal Hot Spring
The “Great Pagosah Spring” which feeds mineral water to our 23 soaking pools, won the Guinness World Record title of The World’s Deepest Geothermal Hot Spring, on August 20, 2011. The Mother Spring measured at an astounding 1,002 feet deep! However, no one really knows just how deep the hot spring is. Every time the spring has been measured, the plumb line ran out before reaching the bottom.
The water from the “Mother” Spring is approximately 144°F and is a turquoise pool approximately 35 feet across with an average depth of 20-30 ft. About 15 feet from one edge, there is a hole in the bottom, measuring two feet in diameter. This is the main spring that reaches an unknown depth. It is the spring in which Guinness World Records®’ hydrologist measured the depth.
