'''Rocky Peak''', located in '''Rocky Peak Park''', is the fourth-highest point in the Santa Susana Mountains, and overlooks the San Fernando Valley and Chatsworth, the Simi Hills, and the Simi Valley in Southern California. The peak, which is {{convert|2715|ft|m|0}} in elevation, sits on the Los Angeles County–Ventura County line.

==Geography== Rocky Peak also marks the point where the county line changes direction from true north to a more northwesterly direction. A large railroad spike driven into the rocks mark this exact spot on the county line. Rocky Peak, which gets its name from the many large craggy boulders that dot its surface, can be viewed from several locations along Topanga Canyon Blvd., and from California State Route 118, also known as the Ronald Reagan Freeway.

The nearest neighbor is Oat Mountain, the highest mountain in the Santa Susana Mountains range, which lies east of Rocky Peak.

==History== The area was part of the homeland and trading crossroads of the Tataviam, Tongva, and Chumash people for eight thousand years.<ref>{{cite web |url=https://www.usatoday.com/tech/science/discoveries/2006-03-03-prehistoric-mill_x.htm |publisher=USA Today |title=Prehistoric milling site found in California article USA Today |accessdate=2014-12-28}}</ref> The Chumash Burro Flats Painted Cave is just to the west in the Simi Hills on the Santa Susana Field Laboratory property.

Historic Santa Susana Pass is at the foot of the mountain, with the Old Santa Susana Stage Road located in the Santa Susana Pass State Historic Park nearby. Rocky Peak has been prominently featured in many classic Hollywood films, being next to three major Movie ranches; the Iverson, Spahn, and Corriganville Ranches; and its evocative 'Old-West Frontier' landscape scenery.
