The ground is bleeding. A red river cuts a path through a bleached valley, winding toward a lake that is no longer there. Seen from the air, the river and its dry terminus appear otherworldly. In actuality, this terrain is located in Owens Valley, an arid stretch of land in southeastern California, between the Sierra Mountains and the White-Inyo Range. The history of this region is the stuff of California legend: a story of engineers, politicians, and big land owners working together to divert water to the rapidly growing desert city of Los Angeles, generating a thriving agricultural industry and an environmental disaster in the process.
