Quick Summary

The Guadalupe Mountains are a mountain range located in southern New Mexico and western Texas, forming the southern extension of the Sacramento Mountains. The highest point in this range, and also the highest point in Texas, is Guadalupe Peak, which stands at 8,749 feet (2,667 meters). These mountains are part of an ancient, horseshoe-shaped fossil reef known as the Capitan Reef, which formed approximately 250 million years ago beneath a tropical ocean.123

The Guadalupe Mountains National Park is situated in this rugged mountain mass within the Chihuahuan Desert. The park showcases the exposed limestone reef, with features like El Capitan (8,078 feet) and Guadalupe Peak. The ecosystem transitions from desert flora and fauna in the surrounding areas to forests of ponderosa pine, aspen, and Douglas fir in the higher elevations.3
