Butterfield Springs
Butterfield Springs flows at 75 degrees Fahrenheit in Lincoln County near Pioche, emerging 21 degrees above ambient at 5,320 feet elevation. Recent USGS sampling documented water at 16.1 degrees Celsius with neutral pH of 7.3 and calcium-magnesium chemistry showing 47 milligrams per liter calcium and 22 milligrams per liter magnesium, with notably low sodium at just 6 milligrams per liter. The spring sits 24 meters from the nearest road, providing roadside access to this modest thermal feature.
At 5,320 feet in eastern Nevada's Great Basin highlands, the spring emerges in pinyon-juniper woodland characteristic of mid-elevation mountain slopes. The terrain receives 9 inches of precipitation and 25.7 inches of snow annually, supporting scattered trees and mountain shrubs in a landscape where ambient temperatures average 54.2 degrees Fahrenheit. The spring sits in rugged country defined by north-south trending ranges separated by broad valleys, with Pioche's historic mining district visible to the northeast. Limestone and volcanic rocks dominate the geology, creating the fractured aquifer systems that feed the thermal discharge.
Access via unpaved roads from Pioche; verify current conditions before departure as mountain weather can close routes during winter and spring. Temperature of 75 degrees Fahrenheit makes this a warm rather than hot spring, suitable for tepid soaking if pools exist. Best visited May through October when roads dry and temperatures moderate. Combine with exploration of Pioche's mining heritage sites. Carry detailed maps as cellular coverage remains limited across Lincoln County's backcountry.
The name likely references the Butterfield Overland Mail route that operated from 1858 to 1861, though specific documentation linking this spring to the stagecoach service remains unclear in available records. Lincoln County's thermal features saw limited development compared to more accessible Nevada springs, with ranching representing the primary historical use of spring water in this remote region.
The water at Butterfield Springs is slightly alkaline (pH 7.3).

Butterfield Springs sits at 5,320 feet above sea level, way above the mile-high mark. You may not feel the altitude strongly, but hot water still dehydrates you faster at elevation. UV is about 21% stronger than at sea level, so bring sunscreen and drink more water than you normally would.
