Description
This map depicts the geology of the Lewis Springs 7 ½' Quadrangle, which is located in the upper San Pedro Valley a few miles north of the U.S. – Mexico border. The quadrangle covers much of the piedmont west of the San Pedro River and south of the Babocomari River, including the eastern fringe of Sierra Vista and a portion of the Fort Huachuca Military Reservation. The quadrangle also covers about 10 miles of the San Pedro Riparian National Conservation Area along the river, and bedrock hills and a small portion of the piedmont east of the San Pedro River. The geology of the quadrangle is diverse and includes Cretaceous sedimentary and igneous rocks, extensive exposures of the upper part of the late Cenozoic basin-filling deposits, and Quaternary surficial alluvium deposited by tributary streams and the San Pedro River. This map is one of 7 1:24,000-scale geologic maps that have been completed recently in the upper San Pedro Valley. Other maps cover the Fairbank (Ferguson et al, 2006), Land (Shipman and Ferguson, 2005), St. David (Youberg, 2005), Huachuca City (Pearthree, 2003), McGrew Spring (Shipman and Ferguson, 2003), and Benson (Youberg et al, 2004) quadrangles
