Eaton Canyon

The canyon has been part of the homelands of the Tongva for thousands of years. The village of Puntitavjatngna relied on the freshwater of the canyon to thrive, housing about 500 to 1,500 dwellings. Spanish settlers arrived in the area in the late eighteenth century and referred to the canyon as "El Precipicio" because of its steep gorges, the canyon falls under several governmental jurisdictions. In August 1877, naturalist John Muir set out from Pasadena for an expedition into the San Gabriels. He writes: "On the first day of my excursion I went only as far as the mouth of Eaton Canyon, because the heat was oppressive, and a pair of new shoes were chafing my feet to such an extent that walking began to be painful." In October 1993, the Kinneloa Fire, begun accidentally on the slopes above Eaton Canyon, burned much of the area as well as more than a hundred homes in neighboring Altadena and Kinneloa Mesa as part of a rash of late October wildfires driven by Santa Ana winds in Southern California. One man died of complications from smoke inhalation and dozens were injured. After briefly serving as the incident command post for the fire, the Eaton Canyon Nature Center was destroyed. It was rebuilt in 1998. In 2022, a property overlooking the canyon was returned to the Tongva tribe via the Tongva Taraxat Paxaavxa Conservancy, which marked the first time the tribe had land in Los Angeles County in nearly 200 years. In 2025, the Eaton Fire consumed the Eaton Canyon Nature Center and burned much of the canyon. ==Landmarks==

Eaton Canyon Natural Area Park The Eaton Canyon Natural Area Park is located where the mountain stream debouches into the foothill wash at the base of the San Gabriel Mountains. The park is administered by the Los Angeles County Department of Parks and Recreation. The county administers the lower two-thirds of the area below the toll road bridge. Most of the 190 acres (0.8 km2) that comprises the natural area lie on the northern boundaries of the old Rancho San Pascual and Rancho Santa Anita on land designated for the Southern Pacific Railroad. Once the railroad gave up the land, it was opened for homesteading. The center was burned down again during the Eaton Fire in January 2025. The staff was unable to evacuate the reptiles in their care and lost several valuable items. Pasadena and parts of Altadena receive about 40% of their water from local sources. John Muir once described the waterfall as "a charming little thing, with a low, sweet voice, singing like a bird, as it pours from a notch in a short ledge, some thirty or forty feet into a round mirror-pool." Several waterfalls also exist above Eaton Fall, which are more secluded. Until 1979, there was a tunnel which allowed access, but this has been dynamited and filled in. While the upper falls were accessible decades ago, there are no longer any maintained trails. People have been injured and killed trying to make these climbs via unofficial trails. In 2011, a man fell to his death on the hike to the falls. Another man fell to his death one week later. In 2013, two hikers attempted to climb to the second waterfall, but decided against it mid-climb. As they were coming down, they both lost their footing and fell. One hiker fell to her death, and the other was airlifted to a hospital. On June 27, 2014, the US Forest Service announced plans to close the trail to the upper falls. The trail to the upper falls was closed off on August 1, 2014. Violators caught trespassing the off-limits area will face a fine of up to $5,000 or six months in jail. Members of the Coalition of American Canyoneers would like access to the area that is closed. • - Eaton Canyon falls Golf course The Eaton Canyon Golf Course is a regulation 9-hole course featuring narrow fairways and rolling terrain. It is administered by the Los Angeles County Department of Parks and Recreation and has been open since 1962. It was originally planned as an eighteen-hole facility and was designed by famed golf course architect, William Francis Bell (known as Billy Bell Jr., son of famed golf course designer, William Park Bell). Opening day ceremonies included a golf outing with dignitaries and local golf professionals, including 1961 PGA Champion, Jerry Barber. On its way to the Rio Hondo, the Eaton Wash is joined by the combined drainages from Pasadena Glen and Hastings Canyons. These channels have all been modified by flood control dams near the base of the mountains, and both have been confined to manmade channels or storm drains in their lower reaches. Typically the Eaton Wash and Arroyo Seco carry very little water. Peak discharges are typically less than 1,000 ft3/s (30 m3/s) for Arroyo Seco and less than 500 ft3/s (15 m3/s) for Eaton Wash. • - Eaton Wash, USGS El Monte (CA) Eaton Canyon Reservoir and Dam Eaton Wash Reservoir and the Eaton Wash Dam were built in and are controlled by the Los Angeles County Department of Public Works. The dam is a rock fill, in height, and is in length. Normal storage for the reservoir is . It has a surface area of and drains an area of . Its primary usage is for flood control and debris storage. • - Eaton Canyon Reservoir • - Eaton Wash Dam ==See also==
