About this map

Watsonville and the fertile lowlands of the Pajaro River valley serve as the focal point for this mid-century geographical study. The landscape is defined by the sharp transition between the alluvial plains of the Bolsa del Pajaro and the complex geological formations of the Santa Cruz Mountains to the east. One of the map's most significant features is the San Andreas Rift Zone, which cuts diagonally across the terrain, influencing the drainage patterns of Gaffey Creek and Casserly Rd.

Agricultural and industrial development is evident in the concentration of lakes and reservoirs, such as College Lake and Lake Tynan, as well as the active Quarry sites near Aromas. The transportation network of the Southern Pacific railroad connects key nodes like Watsonville Junction and Pajaro, while high-elevation landmarks such as Atherton Peak and Mt Madonna provide a clear view of the surrounding tri-county border region.
