About this map

Mason Valley's industrial and agricultural landscape is captured here during the mid-1980s, centered on the city of Yerington and the intensive mining operations of the Singatse Range. The most prominent feature is the massive Yerington Mine, including its tailings and a significant open pit west of the city. To the west, the mountains are honeycombed with extractive history, from the Bluestone Mine and Mason Valley Mine in the north down to the Western Nevada Mine and Mc Connell Mine.

Contrasting this heavy industry, the Walker River meanders through the valley floor, supporting settlements like Mason, Weed Heights, and Nordyke. The map documents a complex network of ditches and gaging stations necessary for managing water in this arid region. From Singatse Peak down to the Missouri Flat, the data shows the intersection of high-desert ranching and large-scale copper mining at a pivotal moment in Lyon County's development.
