Afton Canyon's surface water makes it unique in the southern California desert. Known locally as "The Grand Canyon of the Mojave" for its dramatic geological formations, this is the only place where the Mojave River flows above ground year-round - providing significant riparian (riverbank) wildlife habitat amid the desert. Since prehistoric times, the natural bounty created by this water source has made Afton Canyon a focus for living things. Dense willows and cottonwoods shaded the river, and thickets of mesquite produced bean pods for food. The ponds, marshes and streams provided habitat for a wide variety of wildlife species.
