Reconnaissance geochemical maps of mineralized rocks in the Dragoon Mountains Roadless Area, Cochise County, Arizona
The Dragoon Mountains of central Cochise County are one of a group of northwest-trending ranges in southeastern Arizona. The Dragoon Mountains have a broad, low southeastern part; a narrow, moderately high central part; and a broad, high, northwestern part. The Dragoon Mountains Roadless Area, about 55 mi 2 (104 km 2 ) in size, covers most of this northwestern part. The roadless area thus extends from Middle Pass in the southeast to Big Draw in in the northwest, and from the edge of Sulphur Springs Valley in the northeast to the edge of the San Pedro River valley in the southwest, excluding several canyon mouths and other developed areas as shown on figure 1.
