context_page_description: The Guadalupe Mountains are a mountain range located in West Texas and southeastern New Mexico. The range includes the highest summit in Texas, Guadalupe Peak, 8,751 ft, and the "signature peak" of West Texas, El Capitan, both of which are located within Guadalupe Mountains National Park. The Guadalupe Mountains are bordered by the Pecos River valley and Llano Estacado to the east and north, Delaware Mountains to the south, and Sacramento Mountains to the west.
context_section_description: The Guadalupe Mountains reach their highest point at Guadalupe Peak, the highest point in Texas, with an elevation of 8,751 feet (2,667 m). The range lies southeast of the Sacramento Mountains and east of the Brokeoff Mountains. The mountain range extends north-northwest and northeast from Guadalupe Peak in Texas into New Mexico. The northeastern extension ends about 10 miles (16 km) southwest of Carlsbad, near White's City and Carlsbad Caverns National Park; the southwest tip ends with El Capitan about 90 miles (140 km) east of El Paso.  The mountains rise more than 3,000 feet (910 m) above the arid floor of the Chihuahuan Desert. The Guadalupe Mountains are surrounded by the South Plains to the east and north, Delaware Mountains to the south, and Sacramento Mountains to the west.
  The northwestern extension, bounded by a dramatic escarpment known as "The Rim", extends much further into New Mexico, to near the Sacramento Mountains. The range is bounded on the north by Four Mile Canyon; on the east by the valley of the Pecos River; and on the west by Piñon Creek, Big Dog Canyon, Valley Canyon, Middle Dog Canyon, and West Dog Canyon. Much of the range is built from the ancient Capitán Reef that formed at the margins of a shallow sea during the Permian period. The Guadalupian epoch of the Permian period is named for these mountains, and the Capitanian age within this epoch is named for the Capitan reef. For details on the area's geology, see Delaware Basin. As the range is built up almost entirely of limestone, upland areas have little or no surface water. The only significant surface water is McKittrick Creek, in McKittrick Canyon, which emerges from the eastern side of the massif, just south of the New Mexico border. Elevations at the base of the range vary from 4,000 feet (1,200 m) above sea level on the western side to 5,000 feet (1,500 m) on the east. Several peaks on the southern end exceed 8,000 feet (2,400 m).
  The Guadalupe Mountains experience relatively hot summers, calm, mild autumn weather, and cool to cold weather in winter and early spring. Snow storms, freezing rain, or fog may occur in winter or early spring. Frequent high-wind warnings are issued during winter through spring. Late summer monsoons produce thunderstorms. The nights are cool, even in summer.
