2021 Map of Gandolfo Canyon

About this map

Gandolfo Canyon and Ryan Canyon descend from the western uplands toward the broad, flat expanse of the Reese River Valley in this central Nevada study. The landscape is defined by the historic corridor of the Old Overland Rd, which cuts diagonally across the basin, tracing a path that once served as a vital mid-continental transit route. This 2021 update from the U.S. Geological Survey documents the intersection of this historic trail with modern local infrastructure like Rd 215. The grid layout of the Public Land Survey System, including t18n r42e, remains the primary legal framework for the high desert terrain, preserving the relationship between the dramatic canyon topography and the open valley floor.
