1949 Map of Cosio Knob

About this map

San Antonio Mission anchors the southwest corner of this landscape, situated near the headwaters of Mission Creek. The 1949 survey illustrates a region largely defined by the Hunter Liggett Military Reservation, where a network of utility infrastructure including a Telephone Line and an Airfield crisscrosses the varied terrain. The map captures a transitional infrastructure period, where established landmarks like Cosio Knob and the Oat Hills stand alongside the emerging military presence.
