Another view of Casa Grande from Chisos Mountains Lodge. The restaurant building is in the lower left corner. This photograph is also used in Big Bend Vistas.
The caption to the photograph in the book reads: “Casa Grande rises in wooded slopes to a tremendous square-topped monolith of bare rock with sheer, towering cliffs overlooking the visitor center some 2,000 feet below. The volcanic dome of Emory Peak Rhyolite capping the mountain is slow to erode, and forms solid cliffs. Below it, thinly layered Boot Rock surge deposits and air-fall tuffs erode more easily and form gentler slopes. A thin bed of Pine Canyon Rhyolite is near the base with Chisos tuffs below.
Vegetation on the lower slopes is mainly juniper, oak, and piñon, a combination 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.
Each of the volcanic domes on Casa Grande, Toll Mountain and Emory Peak lies above a volcanic vent and so each is an extinct volcano.”
