1949 Map of Point Mugu

About this map

Point Mugu Naval Reservation dominates the coastal wetlands where Calleguas Creek meets the tidal waters of Mugu Lagoon. This 1949 survey illustrates the strategic coastal geography of Ventura County, showing the proximity of naval operations to the diverse terrain of the Santa Monica Mountains. To the west, the alluvial plains of the Rio De Santa Clara are marked by Duck Ponds and a complex drainage system, while the eastern portion of the map rises sharply into peaks like Laguna Pk and Mugu Pk. The winding Roosevelt Highway traces the coastline beneath these steep ridges, providing the primary transportation link between the isolated La Jolla Valley and the broader coastal plain. Deep drainages such as Big Sycamore Canyon and Serrano Canyon cut through the mountains, highlighting the challenging topography that defined early development in this section of the California coast.
