Packsaddle Mountain is a 4,661-foot-elevation (1,421-meter) summit in Brewster County, Texas, United States.

Description

Packsaddle Mountain is a laccolith set in the Chihuahuan Desert where it is a landmark along Highway 118 which skirts the eastern base of the mountain. The mountain is composed of a core of intrusive igneous rock that forced up and breached the roof of light-colored Late Cretaceous sedimentary rock of the Boquillas Formation and the Pen Formation, leaving the strata tilted around the circumference of the core.[5] Based on the Köppen climate classification, Packsaddle Mountain is located in a hot arid climate zone with hot summers and mild winters.[6] Any scant precipitation runoff from the mountain's east slope drains to the Rio Grande via Nine Point Draw, whereas the other slopes drain to Terlingua Creek which is a tributary of the Rio Grande. Although modest in elevation, topographic relief is significant as the summit rises 1,260 feet (384 m) above the surrounding terrain in one mile (1.6 km). The mountain's toponym has been officially adopted by the United States Board on Geographic Names.[3]
