1987 Map of Mason Butte

About this map

Mason Valley agriculture and heavy mineral industry intersect in this late-twentieth-century study of the Nevada landscape near Yerington. The western edge of the map is defined by the steep Singatse Range, where extensive mining activity is documented through numerous prospects, adits, and the State Mine. This industrial footprint extends south toward the massive Tailings and Tailings Pond complexes, illustrating the scale of local extraction operations during this era.
