Pagosa Hot Springs
Pagosa Hot Springs holds local lore as the world's deepest known geothermal spring system, with thermal water emerging near roadside in Archuleta County at 7,100 feet. The 2,860 mg/L total dissolved solids and 58.3°C temperature create heavily mineralized water with high sulfate content of 1,520 mg/L.
The spring system surfaces within the San Juan Basin, where the town of Pagosa Springs developed directly around its geothermal resources. At roadside location just 29 feet from access points, the spring offers immediate visceral contact with intense thermal output. The surrounding landscape reflects high elevation mountain terrain with substantial annual precipitation.
Located on North 14th Street at roadside, this spring requires minimal walking and is accessible year-round despite 83 inches of annual snowfall. The East Fork Campground lies 17 kilometers away and offers riverside camping. Visit during shoulder seasons to avoid peak summer crowds. Parking and access are straightforward from town.
The Ute word 'Pah gosah' forms the spring's name, reflecting indigenous knowledge of this geothermal feature. The town's identity became inseparable from the spring system, with local promotion of the 'deepest' designation driving tourism and settlement patterns for over a century. Geological data confirms exceptional subsurface heat flow.
The water at Pagosa Hot Springs is slightly alkaline (pH 7.7) with 2860 mg/L total dissolved solids.
