1971 Map of Rocky Canyon

USGS Topo · Published 1975

About this map

Guano Valley and its dramatic eastern boundary, the Guano Rim, dominate this 1971 topographical study of Lake County. This arid landscape is defined by its verticality, where the steep escarpment of the rim drops sharply toward the valley floor, revealing the striking feature known as Wagonslide. Human presence in this high desert environment is sparse, centered on the Spalding Ranch and the rudimentary path of Beatys Butte Road, which navigates the terrain between deep incisions like Sage Hen Canyon and Rocky Canyon.
