Reveille Mill Spring flows at 84°F from BLM land in Nye County at 6,422 feet elevation, emerging 32 degrees above the 52°F ambient average in Nevada's central mining belt. Recent USGS analysis documented water at 25°C with alkaline pH of 7.7 and low total dissolved solids of just 143 mg/L, reflecting relatively short residence time or limited water-rock interaction. The roadside location 65 feet from the nearest road provides accessible entry to warm water managed by BLM's Tonopah Field Office.

The spring emerges at 6,422 feet in the Reveille Range country of central Nevada, surrounded by typical basin and range topography where sagebrush-covered valleys separate fault-block mountains. Annual precipitation totals just 8 inches with 25 inches of snowfall, creating high desert conditions where moisture limits all biological activity. The landscape reflects the mining history that has defined this region since the late 19th century, with Tonopah's silver boom creating the infrastructure that opened these remote ranges to development. Federal BLM ownership extends across most surrounding terrain, managed for multiple use including minerals extraction.

History of Reveille Mill Spring

The Reveille Mill name indicates association with ore-processing facilities that utilized the spring water for milling operations, likely during the early 20th century mining boom when Tonopah and surrounding districts produced vast quantities of silver. Mills required reliable water supplies, making thermal springs valuable in this arid region. The mining operations have long since ceased, but the spring continues to flow on public land open to visitors. Current status remains undeveloped, with water emerging naturally rather than through constructed facilities.

Access via unpaved BLM roads that require high-clearance vehicles; verify current road conditions before attempting travel in this remote region. The 6,422-foot elevation brings cold conditions from November through March despite warm spring water. Summer heat combines with limited shade and water to create harsh desert conditions; spring and fall offer the most comfortable visiting windows. Bring abundant water, sun protection, and navigation tools; cell service is unreliable or absent. The 84°F temperature allows comfortable soaking when air temperatures are moderate. Combine with exploration of Tonopah's mining heritage and surrounding ghost towns throughout central Nevada's historic mining districts.
