About this map

Lava flows and water engineering dominate this Owens Valley landscape, where the Los Angeles Aqueduct and numerous canals like the Aberdeen Ditch cut through the arid terrain. The map captures a complex network of resource management, including the Black Rock Fish Hatchery and several drainage projects such as the Blackrock Drain and Bypass Ditch.
