1986 Map of Wilson Canyon

About this map

The West Walker River carves through the dramatic geology of the Singatse Range in this mid-1980s provisional survey of Lyon County. This section of the river creates the namesake Wilson Canyon, a narrow passage where the water moves between the mountain slopes and the broad, agricultural expanse of Mason Valley. The map details the transition from the high peaks of Mount Wilson and the Pine Grove Hills to the alluvial levels of Missouri Flat, where a complex network of ditches supports the valley's landscape. Human activity is marked by scattered extractive efforts, including several prospects and a gravel pit, alongside a gaging station used to monitor the river's flow. Much of the southern terrain is protected within the Toiyabe National Forest, showing the intersection of wild desert range and the managed water systems of the East Walker River basin.
