Description
The Horseshoe Dam quadrangle straddles part of the lower Verde River valley of central Arizona, a north-trending, west-tilted half-graben along the southern edge of the Transition Zone tectonic province (Spencer and Reynolds, 1989). The graben is filled with Miocene sedimentary and volcanic rocks. Elevations in the quadrangle range from 2000' to 4500', and the area is thickly vegetated with upper Sonoran desert flora. The north-facing slopes are generally choked with dense patches of brush, but the south-facing slopes are relatively open. The area can be reached via the Horseshoe Dam road, a graded gravel road accessible to all vehicles, and a number of primitive jeep trails on the west side of Verde River. Most of the country east of Verde River is either roadless or part of the Mazatzal Wilderness area.
