Cook Spring
Cook Spring flows at 70°F near Socorro in central New Mexico, with USGS-confirmed temperature of 22.5°C and notably elevated iron content at 580 µg/L — among the highest iron readings in the state's thermal springs. Total dissolved solids reach 264 mg/L with sodium-dominant chemistry at 65 mg/L. The spring sits at 4,913 feet and is a short walk from the road.
The spring occupies the arid Rio Grande Rift basin south of Socorro, where the terrain flattens into broad alluvial plains interrupted by isolated volcanic mesas. At this low elevation, creosote, saltbush, and sparse desert grass dominate the landscape. Annual precipitation averages just 8.2 inches, and snow rarely accumulates beyond 8 inches. The Magdalena Mountains rise to the west, while the Rio Grande corridor lies several miles to the east, flanked by cottonwood bosque.
Cook Spring appears in the 1980 NOAA thermal springs inventory and USGS geochemical records. The Socorro area sits atop an active magma body identified by geophysicists, which drives the regional geothermal gradient and explains the area's concentration of thermal springs. The town of Socorro, whose name means 'help' or 'aid' in Spanish, was named by Don Juan de Onate's expedition in 1598. Specific historical records about Cook Spring's naming or early use are limited.
Water Canyon Campground in the Magdalena Mountains sits 18 km away at 6,800 feet — a significant elevation and temperature change from the spring. Spring and fall are ideal; summer temperatures at the spring regularly exceed 100°F. The area receives minimal shade, so bring sun protection and ample water. No permits are known to be required. Socorro provides full services including fuel, food, and lodging.
