The Mother Spring in Colorado

By Linda Tancs

Certified by Guinness World Records as the world’s deepest geothermal hot spring aquifer, the Mother Spring in Pagosa Springs, Colorado, is indeed the mother of all springs. It isn’t a site for soaking or bathing, considering that its depth is at least 1,002 feet (based on at least one instrument of measure) although no one has been able to get to the bottom of it (no pun intended). It acts as a feeder spring for other popular sites in the region, like Springs Resort and Spa (home to the most geothermal hot spring pools in Colorado) as well as several free “hippy dip” springs along the San Juan River.
