CASA GRANDE. Casa Grande is a prominent mountain on the east side of the basin of the Chisos Mountains of Big Bend National Park in Brewster County (at 29°16' N, 103°17' W). The name Casa Grande (Spanish for "Big House") probably refers to the massive profile the mountain presents. Casa Grande rises in wooded slopes to a tremendous square-topped monolith of bare rock with sheer, towering cliffs overlooking the National Park Service ranger station in the basin some 2,000 feet below. At its highest point Casa Grande reaches an elevation of 7,325 feet above sea level. Casa Grande is a lava-capped erosional remnant with constituent stones that are 30 to 33 million years old. The vegetation on its lower slopes is dominated by an association of juniper, oak, and piñon that is found at higher elevations in many of the mountainous areas of the Trans-Pecos region. Some Douglas firs also grow on the upper slopes of the northeast side of the mountain.
