Dianas Punch Bowl
Dianas Punch Bowl discharges 138°F water at 6,757 feet elevation through a cup-shaped depression approximately 50 feet in diameter atop a travertine dome about 600 feet across. The spring emerges 89.9°F above ambient air temperature just 20.1 meters from the nearest road in Eureka County, creating one of Nevada's most visually dramatic geothermal features with hot water pooling about 30 feet below the rim of the bowl-shaped formation.
The spring occupies high desert country where Basin and Range faulting intersects carbonate bedrock, allowing superheated groundwater to surface and deposit the calcium carbonate that built the distinctive dome-like hill. At 6,757 feet elevation, the site receives 9.1 inches of annual precipitation and substantial winter snowfall (38.4 inches), with average air temperatures of 48.1°F creating a landscape of sagebrush and scattered juniper. Recent USGS measurements showed slightly acidic pH (6.7) and moderate mineral content typical of deep-circulation thermal waters dissolving carbonate rock formations.
The spring's name reflects the bowl-like depression formed by thousands of years of travertine deposition around the thermal vent, though it is also called the Devil's Cauldron in some sources. The distinctive landform would have been noted by Indigenous peoples, miners, and ranchers moving through this region, though specific documentation of naming history remains limited. The geothermal feature sits on a small fault that provides the pathway for deep groundwater circulation.
Roadside proximity allows easy viewing, but the steep-sided travertine formation and extreme water temperatures make this spring dangerous for close approach. Winter snowfall can close access roads; summer through early fall provides the most reliable access at this elevation. The feature is best appreciated visually from a safe distance. High-clearance vehicles recommended for surrounding backcountry roads. Bring layers for elevation and changeable mountain weather.
