dc.descriptionAbstract: The Flatiron Mountain 7.5' Quadrangle is located approximately 70 km (40 miles) west of downtown Phoenix, and is just north of Interstate Highway 10. The map area includes the southeastern part of the Belmont Mountains and many isolated bedrock hills south and southeast of the Belmont Mountains. Most of the quadrangle, however, is underlain by Quaternary surficial deposits. Jackrabbit and Coyote washes, heading in the proximal piedmonts of the Big Horn Mountain northwest of the study area, are the major drainages. Jackrabbit Wash is incised up to four meters into older Pleistocene deposits. Coyote Wash flows around the Belmont Mountains and diverges into multiple channels to the south. The channels and floodplains of Coyote Wash are less incised than Jackrabbit Wash. Smaller tributary washes on adjacent older Pleistocene deposits generally are not incised more than two meters. Older Hassayampa River deposits are found along the eastern side of the quadrangle.
