Rizzi Ranch Hot Spring
Rizzi Ranch Hot Spring discharges at 106°F from Federal land within Humboldt National Forest, 267 meters from the nearest road in Elko County. Recent USGS analysis recorded 41°C water with neutral pH 7.4, moderate sodium content (110 mg/L), and low chloride (4.4 mg/L). The spring runs 61 degrees warmer than the 45°F ambient temperature at this Forest Service location.
The spring sits at 5,808 feet elevation in the mountains of northern Nevada's Elko County, within the Humboldt National Forest boundary. At this elevation the landscape transitions from sagebrush steppe to mixed conifer forest, with annual precipitation reaching nearly 20 inches and snowfall totaling 84 inches. The thermal discharge occurs in terrain managed for multiple uses including grazing and mineral extraction under Forest Service jurisdiction. The nearest populated area is Elko, while the spring itself occupies backcountry accessible only by trail or cross-country travel.
Access requires a short walk of approximately 875 feet from the nearest drivable road across uneven terrain. Visit May through October to avoid the 84 inches of annual snow that blankets the area in winter. The 106°F temperature is suitable for soaking after minimal cooling. Confirm current Forest Service access policies before visiting, as extractive use activities may periodically affect the area. Combine with other thermal features in the region on multi-day backcountry trips.
The spring takes its name from the Rizzi Ranch, a historic ranching operation in this portion of Elko County. No documentation exists regarding Indigenous use or early Euro-American discovery dates. The Forest Service assumed management when Humboldt National Forest boundaries were established in the early 20th century. The spring remains in natural condition with no development infrastructure or visitor facilities constructed at the source.
The water at Rizzi Ranch Hot Spring is slightly alkaline (pH 7.4).
