About this map

Tucson pushes northward toward the Santa Catalina foothills in the late 1950s, revealing a landscape defined by rapid mid-century growth and specialized mountain enclaves. The northern edge of the city is a dense network of suburban development and institutions, including the University of Arizona Farm and the historic site of Ft Lowell. Education is a major presence, with diverse campuses ranging from the Academy of the Sacred Heart to the Arizona Desert School.

Rising sharply from the desert floor, the Coronado National Forest hosts high-altitude settlements like Summerhaven and Loma Linda. This era captures a unique blend of Cold War utility and mountain leisure, evidenced by the Mt Lemmon Air Force Sta standing near Numerous mountain springs and the Hartman-Homestake Mines. The transition from the Rillito River valley to Pusch Ridge illustrates the dramatic topographical shift that has long shaped the development of the Pima County region.
