Casa Grande Spring
Casa Grande Spring emerges at 72 degrees Fahrenheit in the high desert transition zone where Great Basin and Mojave influences meet. The 13-degree thermal anomaly reflects geothermal activity at this elevation in northwestern Arizona.
The spring rises at 4,875 feet elevation on State Trust Land, with 437 meters of desert scrub separating it from the nearest road. Typical high desert landscape surrounds the site, with sagebrush and pinyon-juniper woodland characteristic of this climate zone.
Casa Grande Spring sits in Mohave County's geologically complex terrain where thermal waters indicate subsurface heat sources. The spring's name references its location and historical significance to the region's settlement patterns.
Access requires a short walk from North Lookout Canyon Road, though public access remains restricted on State Trust Land. Elevation and isolation mean cooler nights even in summer, with annual precipitation of 11 inches.
