About this map

The Virginia Range dominates the southern portion of this region along the boundary of Washoe and Storey counties, where the high desert terrain transitions into steep ridges and canyons. The northern portion of the landscape is bisected by a prominent transportation corridor that follows the valley floor, connecting the small settlements of Clark and Thisby. This corridor is defined by the proximity of modern infrastructure to historic routes like Canal Rd, which traces the contours of the local waterways and irrigation efforts essential to the area. Further south, the remote character of Post Canyon suggests the difficulty of the terrain, while the township and range lines—specifically t20n r22e and t19n r23e—provide a rigid grid over the undulating natural topography of the Great Basin.
