An unnamed 84-degree spring emerges just 54.6 meters from County Road 217 near Alturas in Modoc County, California, at 4,580 feet elevation. Recent USGS analysis measured 29.8°C with dilute alkaline water showing just 161 mg/L total dissolved solids and pH of 7.6. The spring maintains temperatures 32.1 degrees above ambient.

The spring discharges in the high desert country of northeastern California's Great Basin, technically across the border from Nevada though listed in Nevada records. The elevation and climate create conditions distinct from lower Nevada basins, with 10.9 inches annual precipitation and 33 inches of snow. Average air temperature reaches 51.9 degrees. The roadside location along County Road 217 provides immediate access. Surrounding terrain supports sagebrush steppe with bunchgrass communities.

History of Spring

The lack of a specific name suggests this spring was cataloged in the 1980 NOAA inventory without documented historical use. The location near Alturas places it in California's least populated county. The water chemistry indicates relatively pure thermal water without extreme mineralization.

The roadside location eliminates hiking requirements. County Road 217 may require high-clearance vehicles depending on maintenance conditions. Spring and fall provide moderate temperatures. Winter can bring significant snow at this elevation. The 84-degree temperature may be suitable for bathing if pools exist. Verify current access and land ownership before visiting this remote northeastern California location.
