Diamond Bar and Chino Hills meet the dense suburban grids of Yorba Linda and Placentia in this modern topographic record of the northern Santa Ana River valley. The landscape is defined by the dramatic interface between developed neighborhoods and the rugged open space of the Puente Hills. Narrow corridors like Carbon Canyon and Telegraph Canyon slice through the high ground, providing natural buffers between sprawling residential communities. This era of the landscape shows the complex infrastructure required for regional growth, from the Anaheim Union Reservoir and Anaheim Union Canal to the industrial presence of Brea Chem. Smaller enclaves such as Sleepy Hollow and Carlton are visible among the major thoroughfares of Imperial Hwy and Bastanchury Rd, while Gilman Peak remains a prominent landmark overlooking the intersection of Los Angeles, Orange, and San Bernardino counties.
