About this map

Casa Diablo Mountain and the surrounding Volcanic Tableland dominate this section of the High Sierra region within the Inyo National Forest. The landscape is defined by its complex geology and water management infrastructure, most notably the Owens River Gorge. This steep canyon is traced by the Owens Gorge Pipeline and features significant engineering works like Tunnel Number One and Tunnel Number Two.

Logistical routes such as the Old Sherwin Grade and Casa Diablo Road suggest the historical difficulty of navigating this terrain. Small outposts like Mesa Camp provide rare points of human settlement amidst the broad expanses of Chidago Canyon and Sherwin Hill. The map also captures several natural water sources, including Antelope Spring and the Owens River, which are critical features in this arid, high-elevation environment.
