Buckhorn is a populated place name along State Route 126 in a rural unincorporated area of Ventura County, California, United States. Buckhorn is about 2 miles (3.2 km) outside the town of Piru but is within the eponymous census-designated place. Located in the Santa Clara River Valley, this was an early stagecoach stop and a regular eating place known for being midway between Los Angeles and Santa Barbara. It was run by the Warring family who came to the county in 1869 and owned the nearby Buckhorn Ranch. Buckhorn was also a station on the initial route of the coast rail line that arrived in the valley in 1887. With the completion of the Santa Susana Tunnel in 1904, the route through Oxnard and Simi Valley became the most direct route between Los Angeles and San Francisco. The shipping of agricultural products such as citrus continued to keep this route busy for many years. The Santa Paula branch line no longer connects through to Santa Clarita after the rails were washed out. The junction with the main line is near the East Ventura station.
Simi Valley is a synclinal valley in Southern California in the United States. It is an enclosed or hidden valley surrounded by mountains and hills. It is connected to the San Fernando Valley to the east by the Santa Susana Pass and the 118 freeway, and in the west the narrows of the Arroyo Simi and the Reagan Freeway connect to Moorpark and Ventura, California. The relatively flat bottom of the valley contains soils formed from shales, sandstones, and conglomerates eroded from the surrounding hills of the Santa Susana Mountains to the north, which separate Simi Valley from the Santa Clara River Valley, and the Simi Hills.
The Chalk Hills are a north–south-running low 'mountain' range in the San Fernando Valley perpendicular to and adjoining the Santa Monica Mountains. They are located in the Woodland Hills District of the City of Los Angeles in Southern California. They run between DeSoto and Winnetka Avenues, from south of Ventura Boulevard north to near Victory Boulevard.

The Chico Formation is a geologic formation of the Campanian Age during the Cretaceous Period, found in California and southern Oregon.
The Sespe Formation is a widespread fossiliferous sedimentary geologic unit in southern and south central California in the United States. It is of nonmarine origin, consisting predominantly of sandstones and conglomerates laid down in a riverine, shoreline, and floodplain environment between the upper Eocene Epoch through the lower Miocene. It is often distinctive in appearance, with its sandstones weathering to reddish-brown, maroon, pinkish-gray, tan, and green. Since many of its sandstones are more resistant to erosion than many other regional sedimentary units it often forms dramatic outcrops and ridgelines in many local mountain ranges.
Santa Susana Depot is a train station building located near the Santa Susana Pass in Simi Valley, California. Originally located on Los Angeles Avenue at Tapo Street, the depot opened in 1903. The station was named after the Santa Susana Mountains at the east end of the Simi Valley. The Southern Pacific Railroad used the double-"N" spelling of Susanna on the depot sign facing west, and the single-"N" spelling of Susana on the sign facing east. The Santa Susana Tunnel opened the next year, reducing the distance and transit time between Montalvo and Burbank on the Coast Route linking Los Angeles and San Francisco. Plans and construction for the building were based on Southern Pacific Railroad standard design Two Story Combination Depot No. 22. The depot served the community of Rancho Simi as a passenger station, telegraph office, and freight depot where farmers could deliver crops for shipping and pick up farming equipment delivered by the railroad.
