Route Overview

The Sonoran Desert around Tucson gives way to the Chihuahuan Desert near the Arizona-New Mexico border. The most dramatic landscape shift occurs at the Texas Canyon rest area (milepost 318), where giant granite boulders create a surreal, alien-like terrain. Near Deming, the Florida Mountains rise abruptly from the valley floor, a stark contrast to the otherwise flat expanse.

• Key Viewpoints: Texas Canyon (Arizona), Rock Hound State Park (NM), Sierra de las Uvas (NM).
• Flora: Saguaro cactus, ocotillo, creosote bush, yucca.
