| This generalized regional geologic map of the Lake Mead National Recreation Area was compiled from the state geologic maps for Nevada and Arizona (see Arizona Geological Survey, 2000; Crafford, 2007). The seven rock-unit colors represent general subdivisions based on geologic origin and geologic age. For a detailed geologic map of the northern part of this map area, see Beard and others (2007).
