Chimney Warm Spring
Chimney Warm Spring discharges at 160°F on BLM property in Eureka County, flowing 104 degrees above the ambient temperature of 56°F at 4,813 feet elevation. Despite the misleading "warm" designation, this spring ranks among Nevada's hottest thermal features, with recent USGS measurements confirming 60°C water. The spring sits 69 meters from a road near Eureka, providing roadside access to water requiring extensive cooling before use.
The thermal emergence occupies low-elevation desert terrain in one of Nevada's driest regions, receiving only 5.9 inches of precipitation and 12.2 inches of snow annually. At 4,813 feet, the landscape supports sparse desert vegetation dominated by shadscale and other salt-tolerant species adapted to arid conditions. The roadside location on BLM land managed by the Tonopah Field Office means the surrounding country remains open to multiple uses including grazing and mineral exploration. No significant water features exist nearby beyond the spring's own outflow, which creates a narrow zone of riparian vegetation.
The "chimney" name likely describes a mineral formation at the source, possibly a travertine or silica deposit built by decades of hot water deposition. Historical documentation specific to this spring remains scarce, though its proximity to Eureka connects it to that town's mining history dating to the 1860s silver rush. Springs in this district served miners, ranchers, and travelers crossing the austere landscape between major settlements. The recent USGS sampling confirms ongoing scientific interest in Nevada's geothermal resources.
The 160°F temperature makes direct contact dangerous and requires substantial cooling infrastructure before recreational use becomes possible. Visitors would need to construct elaborate pool systems allowing cold air to reduce water temperature over significant distance and time. The roadside location offers easy access year-round, though summer temperatures exceeding 90°F in this low desert may make soaking uncomfortable regardless of spring temperature. Winter visits take advantage of cooler ambient conditions. Water chemistry shows moderate mineral content at 405 mg/L TDS, resulting in noticeable taste and feel.
