1949 Map of Point Mugu

About this map

The coastal landscape of Guadalasca and the western Santa Monica Mts meet the Pacific Ocean in this mid-century survey of Ventura County. The western edge is dominated by the Naval Reservation, where the expansive Mugu Lagoon provides a complex wetland environment fed by Calleguas Creek. The terrain shifts abruptly from the marshy lowlands and Duck Ponds of the Rio de Santa Clara coastal plain to the sharp elevations of Laguna Pk and Mugu Pk. This geography necessitated a narrow corridor for the Roosevelt Highway, which hugs the shoreline beneath steep cliffs. Inland, the high La Jolla Valley offers a rare pocket of flatter ground amidst deep drainages like Sycamore Canyon and La Jolla Canyon, reflecting the difficult topography that limited development along this stretch of the California coast during the late 1940s.
