1981 Map of Mt. Lemmon

About this map

Santa Catalina Mountains high country dominates this 1981 survey, centered on the developed crest near Mt Lemmon. The settlement at Summerhaven, including the Summerhaven (Mt Lemmon PO), serves as the primary hub along the Mt Lemmon Highway, surrounded by smaller enclaves like Loma Linda and the historical Hartman Homestead. The landscape transitions from the technical infrastructure of an Observatory, Heliport, and various Radio Towers to the protected wildlands of the Pusch Ridge Wilderness and the Santa Catalina Natural Area. A dense network of springs, such as Bill Williams Spring and Lemmon Rock Spring, supports the high-elevation ecosystem, while geologic landmarks like Cathedral Rock and Window Rock define the southern ridges. Small-scale mining activity is noted at the Mines near Catalina Camp in the northeastern corner.
