1967 Map of Mt. Baldy

USGS Topo · Published 1988

About this map

San Antonio Dam and its expansive Percolation Basin dominate the lower foothills, managing the runoff from the high ridges of the Angeles National Forest. This 1967 survey, later revised to include the suburban growth of Upland and Claremont in purple, illustrates the sharp boundary between the residential valley and the steep canyons of the Cucamonga Wilderness. In the north, the village of Mt Baldy and the settlement at Barrett serve as gateway points to the mountains, while the lower slopes host institutional landmarks like the Padua Hills Theater and Scudder-Oaks Sch. The terrain is marked by a complex network of drainages including San Antonio Creek and Cucamonga Creek, which carved the landscape long before the modern expansion of San Antonio Heights pushed against the protected boundaries of the San Dimas Experimental Forest.
