2011 Map of Signal Mountain

About this map

The Big Sandy River meanders through this arid Mohave County landscape, carved by a network of ephemeral drainages and canyons. The prominent landmark Signal Mountain overlooks a terrain defined by deep incisions such as Arrastra Canyon and Hackberry Canyon. Vital water sources are scattered across the desert, including Greenwood Spring, Hackberry Spring, and the appropriately named Big Sandy Spring. Connectivity is limited to foundational routes like 17 Mile Rd in the north and Alamo Crossing Rd in the southwest. This area illustrates the classic desert hydrology of the American Southwest, where washes such as Government Wash and Madril Wash indicate seasonal flow patterns toward the primary river channel.
