1965 Map of Rock Spring Table

USGS Topo · Published 1968

About this map

Camp McGarry (Ruins) and the adjacent Summit Lake Cem anchor the southeastern corner of this high-desert landscape in northern Humboldt County. The terrain is defined by the massive basalt plateau of the Rock Spring Table and the Sheldon Antelope Range, a region shaped by its reliance on dispersed water sources like Rock Spring, Cottonwood Spring, and Chokecherry Spring. The map reveals the infrastructure of mid-century ranching and land management, from the Alkali Ranch to the Wild Horse Pasture and several miles of fence lines. Evidence of early transit and settlement is found in Tollhouse Canyon and along the Old Military Reservation Bdy, while the presence of the Summit Lake Landing Strip suggests the transition to aerial access in this remote territory. The convergence of numerous named springs highlights the critical nature of water in this high-altitude environment.
