Guadalupe Mountains in the context of El Capitan (Texas)

The San Elizario Salt War, also known as the Salinero Revolt or the El Paso Salt War, was an extended and complex range war of the mid-19th century that revolved around the ownership and control of immense salt lakes at the base of the Guadalupe Mountains in West Texas. What began in 1866 as a political and legal struggle among Anglo Texan politicians and capitalists gave rise in 1877 to an armed struggle by ethnic Mexican and Tejano inhabitants living on both sides of the Rio Grande near El Paso against a leading politician, who was supported by the Texas Rangers. The struggle reached its climax with the siege and surrender of 20 Texas Rangers to a popular army of perhaps 500 men in the town of San Elizario, Texas. The arrival of the African-American 9th Cavalry and a sheriff's posse of New Mexico mercenaries caused hundreds of Tejanos to flee to Mexico, some in permanent exile. The right of individuals to own the salt lakes, which had previously been held as a community asset, was established by force of arms.

The conflict began as a local quarrel and grew in stages to finally occupy the attention of both the Texas and federal governments. Newspaper editors throughout the nation covered the story, often with frenzied tone and in lurid detail. At the conflict's height, as many as 650 men bore arms. About 20 to 30 men were killed in the 12-year fight for salt, and perhaps double that number were wounded.

The Arizona/New Mexico Mountains ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S. states of Arizona and New Mexico, with a small extension into the Guadalupe Mountains in Texas.

The Guadalupian is the second and middle series/epoch of the Permian. The Guadalupian was preceded by the Cisuralian and followed by the Lopingian. It is named after the Guadalupe Mountains of New Mexico and Texas, and dates between 274.4 ± 0.4 – 259.51 ± 0.21 Mya. The series saw the rise of the therapsids, a minor extinction event called Olson's Extinction and a significant mass extinction called the end-Capitanian extinction event. The Guadalupian is also known as the Middle Permian.

Carlsbad Caverns National Park is a national park of the United States in the Guadalupe Mountains of southeastern New Mexico. The primary attraction of the park is the show cave Carlsbad Cavern. Visitors can hike in on their own via the natural entrance or take an elevator from the visitor center.

This list of North American deserts identifies areas of the continent that receive less than 10 in (250 mm) annual precipitation. The "North American Desert" is also the term for a large U.S. Level 1 ecoregion (EPA) of the North American Cordillera, in the Deserts and xeric shrublands biome (WWF). The continent's deserts are largely between the Rocky Mountains and Sierra Madre Oriental on the east, and the rain shadow–creating Cascades, Sierra Nevada, Transverse, and Peninsular Ranges on the west. The North American xeric region of over 95,751 sq mi (247,990 km) includes three major deserts, numerous smaller deserts, and large non-desert arid regions in the Western United States and in northeastern, central, and northwestern Mexico.

Guadalupe Mountains National Park is a national park of the United States in the Guadalupe Mountains, east of El Paso, Texas. The mountain range includes Guadalupe Peak, the highest point in Texas at 8,751 feet (2,667 m), and El Capitan used as a landmark by travelers on the route later followed by the Butterfield Overland Mail stagecoach line. The ruins of a stagecoach station stand near the Pine Springs visitor center. The restored Frijole Ranch contains a small museum of local history and is the trailhead for Smith Spring. The park covers 86,367 acres (134.9 sq mi; 349.5 km) in the same mountain range as Carlsbad Caverns National Park, about 25 miles (40 km) to the north in New Mexico. The Guadalupe Peak Trail winds through pinyon pine and Douglas-fir forests as it ascends over 3,000 feet (910 m) to the summit of Guadalupe Peak, with views of El Capitan and the Chihuahuan Desert.

Camping is available at the Pine Springs campground and at Dog Canyon. A public corral for livestock is available by reservation. The park observes Mountain Time.
