Chantry Flat

Santa Anita Dam, also known as Big Santa Anita Dam, is a concrete thin arch dam on Santa Anita Creek in the San Gabriel Mountains of Los Angeles County, California. Owned by the Los Angeles County Flood Control District, the dam serves for flood control, water conservation and debris control. The dam is 225 feet (69 m) high and 612 feet (187 m) long, holding 858 acre-feet (1,058,000 m3) of water with a maximum capacity of 1,028 acre⋅ft (1,268,000 m3). The catchment area for the dam is 10.8 square miles (28 km2). The dam was built between 1923 and 1927. The dam has three valves that control releases of stormwater.The dam is situated in the steep San Gabriel foothills, north of Sierra Madre and Arcadia. It is located just north of the boundary of the Angeles National Forest. The dam is visible from Santa Anita Canyon Road, which runs along the west slope of the Santa Anita Canyon and provides access into trails further upstream along Santa Anita Creek. The viewing window for the dam is very short, only about a half-mile; the access road which runs down into the canyon from Santa Anita Canyon Road is closed to the public. However, the First Water trail, which leads downstream from Chantry Flat along the creek, is said to provide access to the reservoir. Since the 1990s the maximum allowed storage of water has been restricted, to ensure that the dam will not collapse due to seismic instability. This has partially caused rapid silting of the reservoir and sediment removal was started in mid-2009. The reservoir was drained and about 6,750,000 cubic yards (5,160,000 m3) of sediment were removed. A staged rescue at the dam was broadcast in November 1958 as an episode of the syndicated U.S. television series Rescue 8 titled "The Chasm".

Hughes Airwest Flight 706 was a regularly scheduled flight operated by American domestic airline Hughes Airwest from Los Angeles, California to Seattle, Washington, with several intermediate stops. On Sunday, June 6, 1971, the McDonnell Douglas DC-9 serving as Flight 706 departed Los Angeles just after 6 p.m. en route to Seattle as a McDonnell Douglas F-4 Phantom II of the United States Marine Corps was approaching Marine Corps Air Station El Toro near Irvine at the end of a flight from Naval Air Station Fallon in Nevada. The two aircraft collided in midair over the San Gabriel Mountains near Duarte, killing all 49 aboard the DC-9 and the F-4 pilot; the F-4 radar intercept officer ejected and survived. The crash of Flight 706 prompted the United States Armed Forces to agree to reduce the number of military aircraft operating under visual flight rules in civilian air corridors and to require military aircraft to contact civilian air traffic controllers.

The Mount Wilson Toll Road (1891–1936) is a historic roadway which ascended Mount Wilson via a vehicular passable road from the base of the foothills in Altadena. It was accessible from Pasadena via Santa Anita Avenue (nowadays the north-south portion of Altadena Drive) which drove right to the front porch of the toll house. The road is still accessible to non-motorized traffic (hikers, bicyclists, and horses) by way of Eaton Canyon (either from the Nature Center entrance, or an access gate on Pinecrest Drive, just off Altadena Drive in Altadena). Segments of it have been closed at various times due to landslides. A 2005 landslide destroyed 50 yards of the road, but it has since been rebuilt and reopened.Mount Wilson had always been active with human passage starting from the days of the local Native Americans.
