History of This Spring

The Gila hot springs area sits within ancestral Mogollon territory, with evidence of habitation spanning centuries. The region's geothermal activity attracted early Anglo settlers in the 1870s and 1880s. No specific development history is documented for this individual spring vent. The broader Gila thermal system remains one of the most geothermally active zones in southwestern New Mexico.

Extreme caution: water temperature reaches 149°F and direct contact will cause severe burns. This spring is accessible via a short walk from the road. Forks Campground is 3.8 km away with free, first-come sites along the West Fork of the Gila River. Best visited spring through fall; winter snow can make access difficult. Bring plenty of water and sun protection in summer months.
