1934 Map of Cima Mesa

About this map

The San Andreas Fault Zone cuts dramatically across the northern landscape of this 1934 topographic survey, revealing the striking geologic foundations of the High Desert. This advance sheet, produced under County Surveyor Alfred Jones, captures the high-elevation terrain of Cima Mesa before modern development altered the rural character of northern Los Angeles County. The drainage patterns of Pallett Creek and Little Rock Creek dominate the southern half of the sheet, while early transportation routes like Fort Tejon Road and Pallett Creek Road provide evidence of the area's connectivity during the mid-1930s. Isolated infrastructure, including several scattered wells and springs, points to the critical importance of water management in this arid environment.
