South of here is the Old Santa Susana Stage Road, an important road linking Los Angeles and Ventura County. The route climbs through what is now the Santa Susana Pass State Historic Park.To slow down their descent, drivers would chain a wheel in place or use a wooden timber placed through the rear spokes to lock both wheels. Hikers can still see the deep ruts made by the wagons on the Devils Slide section, near the historical marker.The road was designated Los Angeles Historic-Cultural Monument #92 in 1972; listed on the National Register of Historic Places in 1974; and declared Ventura County Historical Landmark #104 in 1986.
