The Santa Clara River valley and its surrounding canyonlands define this landscape in the early 21st century, showing a mix of suburban growth and industrial energy production. The community of Val Verde and the settlement at Castaic anchor the eastern side of the map, while the western reaches remain dominated by topographical relief and named canyons like Santa Felicia Canyon and Lechler Canyon. This period illustrates the extent of petroleum extraction in the region, with the Del Valle Oil and Gas Field, Ramona Oil Field, and Holser Oil Field clearly marked across the hills. Local land ownership is evidenced by several named holdings, including Stanley Ranch, Hathaway Ranch, and Lechler Ranch. Significant infrastructure such as the Valle Training Center Rd and various fire roads like the Santa Felicia Canyon Fire Rd cut through the terrain, providing access to the higher elevations above Lake Piru.
