San Jacinto Ranch Spring
San Jacinto Ranch Spring discharges at 148°F in Elko County near Jackpot, positioned just 3.1 meters from the nearest road at 5,220 feet elevation. The extreme temperature creates water that runs 100 degrees warmer than the 48°F ambient air temperature, requiring extensive cooling before human contact is safe. No recent geochemical data is available for this thermal feature.
The spring emerges in northern Nevada's high country where the Great Basin meets the Jarbidge Mountains, in terrain receiving 13 inches of annual precipitation and 40.5 inches of snow. The landscape consists of sagebrush steppe with scattered juniper and mountain mahogany, transitioning to mixed conifer forest at higher elevations. The spring's roadside location suggests it occurs on or adjacent to ranch property, though specific land ownership details are not documented. The thermal discharge creates a localized zone of warmth in an otherwise cold climate.
The 148°F temperature requires cooling to 110°F or below before soaking is possible, necessitating constructed pools or extensive wait times. Confirm access permission and current conditions, as the spring may be on private ranch property. Visit June through September to avoid heavy snow; winter access is likely impossible. The roadside location provides easy physical access if entry is permitted. Bring thermometer to verify safe temperatures before entering water. High-clearance vehicles may be needed depending on road conditions.
The spring takes its name from the San Jacinto Ranch, a historic livestock operation in this portion of Elko County near the Nevada-Idaho border. No records document Indigenous names or early Euro-American discovery dates. The ranch likely dates to the late 19th or early 20th century when homesteading opened this region to settlement. Current status and development level are not specified in available data.
