It is located in the San Gabriel Mountains, northeast of Mount Wilson, and within the Angeles National Forest. It forms Cogswell Reservoir, which has a capacity of 8,969 acre-feet (11,063,000 m3).The dam serves mainly for flood control in conjunction with San Gabriel Dam and Morris Dam downstream. San Gabriel Dam lies 13 miles (21 km) downstream.

The San Gabriel Wilderness is a wilderness area created in 1968 of more than 36,118 acres (150 km2) within the Angeles National Forest and San Gabriel Mountains National Monument. The area lies on the southern slopes of the San Gabriel Mountains, between the Angeles Crest and the West Fork of the San Gabriel River.The area was originally set aside as the Devils Canyon-Bear Canyon Primitive Area of 35,000 acres (140 km2).The San Gabriel Mountains were first preserved by the federal government in 1892 as the San Gabriel Timberland Reserve, established by U.S. President Benjamin Harrison and influenced by California conservationists, Abbot Kinney and John Muir. This forest reserve would later become part of the Angeles National Forest in which the San Gabriel Wilderness is now located.

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.

Fish Canyon Falls is a tiered waterfall in Los Angeles County, California, located within the Angeles National Forest in the San Gabriel Mountains. The falls are located about 2 miles (3.2 km) northwest of Azusa on the Fish Canyon Creek. The falls drops a total of 80 feet (24 m) in four tiers. Unlike many seasonal waterfalls in Southern California, it has a fairly reliable flow year round, due to springs located further up the canyon. However, it can still dry up during the late summers of dry years. A 4.8-mile (7.7 km) round trip hike provides access to the falls.

Chantry Flat is a designated "Recreation Area" within the Angeles National Forest, about three miles (5 km) into Big Santa Anita Canyon, and is closely associated with the towns of Arcadia and Sierra Madre, CA. The flat itself houses a large public picnic area, and is the starting point for several historic trails of the San Gabriel Mountains, including the 28.5-mile (45.9 km) Gabrielino Trail. The US Forest Service estimates the road to Chantry as the third busiest entry into the Angeles, next to CA State Highways 2 and 39.

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".
