1987 Map of Mason Butte

About this map

The Singatse Range and its high-desert mining landscape dominate the western portion of this Lyon County survey. Extensive mineral extraction is evident through numerous prospect sites and established operations like the Stair Mine and Guild Placer Mines. The transition from the steep industrial terrain of Carson Hill and McLeod Hill to the agricultural flats of Mason Valley is marked by a complex network of irrigation, including the West Campbell Ditch and the Spragg - Alcorn - Bewley Ditch. Near the southern edge, the town of Yerington is depicted with its Municipal Airport and local landmarks like the Drive-In Theater. Large-scale water management is a primary theme, with a massive tailings pond and sewage disposal ponds situated between the hills and the valley floor.
