Mineral Hot Springs
Mineral Hot Springs emerges at 140°F in Saguache County at 7,744 feet elevation in the northern San Luis Valley, where thermal water surfaces just 196 feet from the nearest road in an arid sagebrush landscape.
The spring flows in high desert conditions where sagebrush, cottonwood, and piñon dominate the sparse vegetation. The thermal water emerges in open terrain offering views across the San Luis Valley toward distant peaks. The climate here remains exceptionally dry, with strong sun exposure and minimal cloud cover characterizing the landscape.
Mineral Hot Springs water derives from geothermal circulation beneath the San Luis Valley, one of the most geologically active regions of Colorado with continuing subsidence and heat flow. The spring's modest mineralization with 140 mg/L sodium and 160 mg/L sulfate indicates relatively straightforward ascent from depth in this high-altitude valley setting.
This roadside-accessible spring offers convenient approach in the scenic northern San Luis Valley. Summer and early fall provide ideal conditions, though the location remains accessible during much of the year at this elevation. Minimal facilities exist nearby; stock supplies in Saguache before visiting. The arid climate means bright sun and potential for rapid temperature changes.
