Stoney Point, also known as the Stoney Point Outcroppings or Chatsworth Formation,

Geology

Geologists know Stoney Point as the Chatsworth Formation, which are the giant rock outcroppings in Simi Hills.

It was used as a marker by the Southern Pacific Railroad during construction of the railroad through the Santa Susana Mountains.

Historic site

It was designated a historical Los Angeles Historic and Cultural Monument in 1974, because of its historic and cultural value as well as being deemed one of the "most picturesque places in Los Angeles." The facility features 81 acres of land, including a five-acre equestrian center which was purchased by the City in 2007 and is home to the Annual Chatsworth Day of the Horse Festival hosted by the Chatsworth Neighborhood Council each Spring.

During the land grab that resulted from the McKinley Act, Stoney Point was claimed by the Charlton Family of New York. Stoney Point was the site of the Charlton Quarry, one of three Chatsworth Quarries that was operated by the Bannon Mining Company. "Dimension Stone" was quarried for the nearby train tunnel. Remnants of the quarry can still be found on the eastern side of Stoney Point along the Santa Susana Creek.

Railroad history

Stoney Point functions as mile marker on the Southern Pacific Railroad, which links much of Southern California to Northern California. Stoney Point is located at the base of the Simi/Santa Susana Grade. Stone that was quarried at Stoney Point was used in Chatsworth's train tunnels.

When inhabited by the Gabrielino-Tongva tribe and the missionaries in the early years, the land was prime for agriculture including fruit, vegetables, wheat, and barley. Otherwise, the climbing season at Stoney Point lasts all year. Some people have taken advantage of the easiness of the rock to chip, and have created their own chips by breaking off pieces. Climbers look down upon this practice.
