The Dragoon Mountains are in central Cochise County, between the San Pedro and Sulphur Spring valleys.

The Dragoon Range trends northwesterly, with a length of approximately 26 miles and a width of 3 to 12 miles. Its crest rises 1,000 to 3,000 feet above the adjacent plains and attains a maximum altitude of 7,512 feet. Its slopes are characteristically steep, and the northern portion in the vicinity of Cochise Stronghold is extremely rugged.

Schist, probably of older Precambrian age, crops out immediately west of Courtland and also on the west slope in the vicinity of South Pass.

North of the schist area on the west side of the range is a small exposure of dark greenish porphyritic granite carrying numerous schist fragments.

Bolsa Quartzite of middle Cambrain age overlies the schist and granite in the central and northern portions of the range and at Courtland. Because of faulting, intrusion, and erosion, its maximum observed thickness of 325 feet does not represent its total.

Overlying the Bolsa quartzite is the Upper Cambrian Abrigo Limestone which, on the southwest side of the range has an exposed thickness of approximately 400 feet. In places about 50 feet of yellow and red sandy shale, possibly equivalent to the Cochise formation, separates the Abrigo from the Bolsa.

Above the Abrigo is Devonian Martin limestone which has been recognized chiefly in the southwestern part of the area. There it has a maximum thickness of 355 feet.

The Mississippian Escabrosa Limestone is characterized by medium- to massive beds which, if metamorphosed, tend to form crystalline, relatively pure marble. It shows a thickness of 300 feet in the southwestern art of the range and occurs prominently in the Courtland area.

Pennsylvanian Naco Limestone constitutes part of the Gleeson Ridge, and naco Limestone of Snyder Hill (Permian) aspect is widespread in the main range. These limestones are medium- to thin-bedded, the Pennsylvanian is somewhat cherty, and the Permian is locally impure.

A series from 1,000 to possibly 3,000 feet thick, of shale, sandstone, and basal conglomerate unconformably overlies the Paleozoic rocks, chiefly in the middle segment of the range and north of Courtland. It has been correlated tentatively with the Lower Cretaceous (Comanchean) Bisbee group.

Intruding the Cretaceous and older rocks is the Stronghold granite which occupies an area of more than 50 square miles in the northern portion of the range and extends as irregular masses and great dikes into the older formations. In the southern third of the area, granitic rocks also make up large areas. At Courtland and Gleeson, they include quartz monzonite, quartz-monzonite porphyry, and granite, all of post-Paleozoic age. Dikes of aplite, rhyolite porphyry, felsite, and diabase are common locally.
