1949 Map of Cosio Knob

About this map

Mission San Antonio de Padua stands as a focal point in this 1949 survey of the Monterey County interior, situated just north of the San Antonio River at the foot of the Oak Hills. The landscape is dominated by the Hunter Liggett Military Reservation, which encompasses much of the rugged topography including Cosio Knob and Sulphur Spring. The map reveals a complex system of drainage and ranching land partitioned by the Grant Boundary and traversed by Jolon Road. Notable landmarks like Milpitas and the nearby Landing Strip reflect the mid-century intersection of colonial history and active military operations. Geographers and local historians can trace the paths of seasonal watercourses such as Mission Creek, Jolon Creek, and Ruby Canyon as they cut through the elevated terrain toward the Valley.
