About this map

Morgan Hill anchors the northeastern corner of this 1955 survey, where the Southern Pacific railroad and U.S. Highway 101 parallel the base of the Santa Cruz Mountains. The landscape is defined by the complex hydrology of the region, featuring major installations such as Chesbro Reservoir and Uvas Reservoir, which capture runoff from Little Uvas Creek and Llagas Creek. Purple revision tints from 1968 highlight the post-war suburban expansion creeping toward the hills from the Santa Clara Valley.

In the south, the Mt Madonna County Park preserves high ground near the Santa Clara and Santa Cruz county line. Local education and community life are represented by the Machado School and Adams Sch. Along the western edge, the distinct geological signature of the San Andreas Rift Zone cuts through the canyon country near Redwood Retreat, marking the boundary between the coastal ranges and the agricultural valleys to the east.
