1942 Map of Santiago Peak

About this map

The Santa Ana Mountains dominate this wartime landscape, anchored by the high elevations of Santiago Peak and Modjeska Peak. In the valleys below, the small settlement of Modjeska and the canyon community of Trabuco Oaks reside along the drainage of Santiago Creek and Trabuco Creek. The map documents a critical period of infrastructure before the post-war housing boom, showing the Atchison Topeka and Santa Fe railroad corridor connecting inland points like El Toro to the coastal reach of South Laguna. To the south, the historic mission site of San Juan Capistrano serves as a focal point where San Juan Creek meets Arroyo Trabuco. Strategic military and forest management is evident through the presence of the State Guard Station and the Santiago Lookout, while early recreation is marked by the San Juan Hot Springs in the eastern canyons.
