Warm Spring
A 75-degree spring in Washington County near the city of Washington, flowing at 2,820 feet elevation with 341 mg/L total dissolved solids and calcium-sulfate chemistry. Recent USGS measurements confirm 23.7 degrees Celsius temperature with pH 8.0, emerging just 10.6 degrees above the warm ambient temperature of 64.4 degrees. Roadside access at less than one meter from the road makes this easily reached.
Positioned in Utah's southwestern desert where the Mojave and Great Basin ecosystems converge, the spring emerges in terrain receiving only 8.3 inches annual precipitation with 8.8 inches of snow. The low elevation and southern latitude create mild winters and hot summers in this rapidly urbanizing area of the greater St. George region. Red sandstone formations dominate the landscape, with desert vegetation including creosote bush, blackbrush, and Joshua trees at higher elevations. The Virgin River flows through valleys to the south.
Washington City, established in 1857 as one of Utah's "Cotton Mission" settlements, relied on water resources including warm springs for irrigation in this arid environment. The spring's calcium-sulfate chemistry and moderate temperature suggest it may have served agricultural purposes during pioneer development. The area's rapid modern growth has transformed formerly rural spring locations into suburban landscapes. Generic naming as simply "Warm Spring" indicates no distinctive historical narrative was preserved.
Best visited October through May when desert temperatures are moderate; summer heat regularly exceeds 100 degrees. The roadside position in an urbanizing area suggests potential access complications from development or private land ownership; verify current status before visiting. Red Cliffs Campground, 13.5 kilometers away, offers developed camping in a National Conservation Area with dinosaur tracks, Ancestral Puebloan archaeology, and excellent red rock canyon hiking.

Overview Red Cliffs Recreation Area includes a campground, day use areas, a non-motorized trail system, and interpreted public use sites. Dinosaurs left their footprints, now visible in the sandstone. Ancestral Puebloans lived here in the 10th century, growing corn, beans, and squash along Quail and Leeds Creek. Mid-19th century pioneers farmed here, supplying the area’s silver miners with food. Located within the Red Cliffs National Conservation Area, the Recreation Area is managed to cons...
