About this map

The Santa Clara River valley and the high Santa Monica Mountains define this Southern California landscape at the start of the twentieth century. The map centers on the ranch lands and early agricultural hubs of Ventura and Los Angeles counties, including the historic ranch site at Camulos and the burgeoning rail junctions at Saugus and Newhall. Industrial development is evident in the Oil Canyon and Modelo Canyon areas, where early petroleum extraction was beginning to shape the region's economy.

Transportation networks are heavily anchored by the Southern Pacific Railroad, which follows the river course and tunnels through the Santa Susana Pass. Along the coast, Port Los Angeles appears near Santa Monica, serving as a vital maritime link before the regional focus shifted toward San Pedro. The rugged interior is marked by the Pine Mountain and Zaca Lake Forest Reserve, while the valleys show the layout of ranchos and early settlements like Simi and Newbury Park before the suburban expansion of the later century.
