About this map

Pete Mountain and the Santa Rita Mountains dominate this high-desert landscape along the border of Pima and Santa Cruz counties. The map records a legacy of hard-rock extraction, evidenced by numerous named operations such as the Glove Mine, Montosa Mine, and the Treasure Vault Mine. These mining interests are concentrated among complex drainage systems including Agua Caliente Canyon and Montosa Canyon, where the topography rises sharply toward the summit of Mt Hopkins.

Scientific advancement meets this frontier history at the Smithsonian Astrophysical Observatory, located near the high peaks alongside a dedicated Heliport. Rare local features like the Agua Caliente Caves and the Hermits Home Mine suggest a landscape used for both industry and shelter. Ranching life is represented at Proctor Ranch, while the presence of Graves near Madera Canyon provides a somber genealogical touchpoint for family researchers.
