2018 Map of Harper Canyon
USGS Topo · Published 2018About this map
The Vallecito Mountains dominate this arid landscape, characterized by complex drainage systems and unique geological formations like the Mud Palisades. This 2018 survey detail shows a network of desert washes, including Fish Creek Wash and Alma Wash, which define the movement of water and travelers across the basin. The transition from the high desert of Harper Flat and Hapaha Flat down toward the Lower Borrego Valley reveals the stark topography of eastern San Diego County.
