2012 Map of Casa Diablo Mountain

About this map

Casa Diablo Mountain dominates the high desert landscape of Mono County in this early 21st-century survey. The terrain is defined by a network of seasonal water sources and historical transit routes, including the Old Sherwin Grade and the Lower Rock Creek Rd which wind through the foothills near Sherwin Hill. The presence of Mesa Camp and the Casa Diablo Mine Rd suggests a legacy of seasonal habitation and resource extraction. The Owens River and Lower Rock Cr provide critical drainage through the arid flats, while engineering features like Tunnel Number Two indicate the management of water or transportation through the mountain passes. Modern US Forest Service data reveals a complex grid of fire and access roads such as Sheep Camp Rd and the Chidago Loop that serve the contemporary management of this transition zone.
