2014 Map of Mason Butte

About this map

Greenville and the northern outskirts of Yerington anchor this landscape where the desert floor meets the rising peaks of the Singatse Range. The transition from the alluvial Mason Valley to the rocky heights of Carson Hill and McLeod Hill highlights the complex topography of Lyon County. Water management is the central theme here, evidenced by an intricate network of irrigation channels including the Spragg-Alcorn-Bewley Ditch, Sand Ridge Ditch, and Wabuska Drain, all supporting agriculture in the arid environment. These man-made features weave around the natural course of the Walker River. Local infrastructure is represented by the Yerington Municipal Airport and a grid of rural routes such as Dye Ranch Rd and Miller Ln, illustrating how settlement patterns have adapted to the narrow fertile corridors between the Great Basin ranges.
