Geologic Map of the Phoenix Mountains, Phoenix, Arizona

The Phoenix Mountains, located within the Phoenix metropolitan area of central Arizona, are a northwest-trending, uplifted fault block that extends for about 13 km (8 miles) from Moon Hill in the northwest to Camelback Mountain in the southeast (Fig. 1). The area includes a main range, with 420 m (1,378 ft) of local relief, as well as several isolated peaks. The geologic mapping for this study covers the main part of the range, including (from northwest to southeast) Moon Hill, Shaw Butte, North Mountain, Stoney Mountain, Dreamy Draw, Squaw Peak, and the informally named Quartzite Ridge. The main goals of this study were to document the bedrock geology, reconstruct the geologic history, and produce a 1:24,000 geologic map of the range.
