1979 Map of Las Guijas

About this map

The Las Guijas Mountains dominate the southeastern landscape of this Pima County survey, an area defined by the intermittent drainage of Altar Wash and Arivaca Wash. The map records a working cattle and mining landscape during the late 1970s and early 1980s, marked by scattered water sources like Martinez Well, Lindberg Tank, and Tiohierro Tank that supported local ranching operations such as Figueroa Ranch. Evidence of mineral exploration and extraction is visible throughout the slopes, notably at the Las Guijas Mine and various unnamed Prospects and Drill Holes. The transport network consists largely of unimproved roads and light-duty routes such as Shaffer, highlighting the rural character of the terrain between the Santa Margarita Wash and Arivaca Creek.
