Azure Ridge dominates this arid landscape where the eastern edge of Nevada meets the Arizona border. The terrain is defined by a network of drainage systems, including the Horse Spring Wash and Black Wash in the north, which eventually lead toward the Grand Wash Valley in the southeast. In this corner of the map, the landscape shifts as it reaches the waters of Lake Mead at Grand Wash Bay. The area's volcanic history is quietly noted by the presence of a Lava Bed in the northeastern quadrant, while the presence of Burro Spring and New Spring Wash indicates the critical role of intermittent water sources in this desert environment. This survey captures the region just as modern recreational and environmental management patterns were established around the reservoir.
