Unnamed Thermal Spring
An unnamed 94°F thermal spring in the Gila National Forest, Grant County, New Mexico. Recent USGS measurements recorded 60.6°C (141°F) with a near-neutral pH of 7.8 and total dissolved solids of 505 mg/L. The spring sits at 5,747 feet and requires a 2.2-mile hike from the nearest road.
The spring emerges in the rugged, deeply incised canyon country of the Gila National Forest near Arenas Valley. At 5,747 feet, the terrain supports mixed ponderosa pine and juniper woodland. The West Fork of the Gila River drains the area, carving steep cliff faces and narrow riparian corridors. Annual precipitation averages 15.3 inches with 18.1 inches of snow, producing distinct wet and dry seasons across the mountainous landscape.
The Gila region has been used by Indigenous peoples for thousands of years, with the Gila Cliff Dwellings National Monument located approximately 15 miles to the north. The surrounding forest has seen mining, ranching, and recreational use since the late 1800s. This particular spring lacks specific historical documentation, though the broader Gila hot spring system has drawn visitors since at least the early territorial period.
Reach this spring via a 2.2-mile hike through Gila National Forest backcountry. Sturdy footwear and topographic maps are recommended, as trail conditions vary seasonally. Forks Campground lies 8.6 km away along the West Fork of the Gila River with first-come, first-served sites. Winter brings snow at this elevation; spring and fall provide the most comfortable hiking weather. No permits are required for day use.
