2018 Map of Lake Forest

About this map

Loma Ridge and the southwestern edges of the Cleveland National Forest dominate this landscape, where rugged canyons meet the dense residential expansion of south Orange County. The map captures a sophisticated network of transportation and water management, featuring several wash systems like Borrego Canyon Wash and Hicks Canyon Wash alongside the Siphon Reservoir. The transition from the undeveloped heights of Limestone Canyon to the master-planned communities of Irvine and Lake Forest is stark, illustrating the modern suburban character of the region. Local heritage is preserved in landmarks such as El Toro Memorial Park and the site of Tomato Spring, reflecting the area's agricultural and ranching roots before it became a hub of technology and residential development. To the east, the terrain rises sharply into named peaks and canyons including Modjeska Canyon and Harding Canyon, defining the geographic boundary of the Los Angeles Basin.
