Guadalupe Peak, Mountain summit in Guadalupe Mountains National Park, Texas, US

Guadalupe Peak is a mountain summit in Guadalupe Mountains National Park in West Texas that rises 2667 meters (8751 feet) above sea level. The summit offers views over the Chihuahuan Desert and the surrounding mountain ridges that extend north and south.

The mountain served as a navigation point for travelers along the Butterfield Overland Mail route during the 19th century western expansion of the United States. The route connected Missouri with California and carried mail and passengers through this remote region.

At the summit stands a stainless steel pyramid erected by American Airlines in 1958 for the 100th anniversary of the Butterfield Overland Mail stagecoach route, which passed south of the mountain. One face bears the American Airlines logo, another a U.S. Postal Service tribute to the Pony Express Riders of the Butterfield Stage, and a third a compass with the Boy Scouts of America logo. The Mescalero Apaches regard the peak as one of four sacred mountains.

The trail to the summit begins at Pine Springs Campground and covers 13.5 kilometers (8.4 miles) round trip with an elevation change of about 914 meters (3000 feet). Most hikers need five to eight hours for the entire route and should start early in the morning to avoid afternoon weather.

The Mescalero Apache regard Guadalupe Peak as one of four sacred mountains. The stainless steel pyramid at the top, placed by American Airlines in 1958, carries three emblems: the airline's logo, a U.S. Postal Service tribute to the Pony Express Riders of the Butterfield Stage, and a compass with the Boy Scouts of America logo.
