Eaton Canyon is a major canyon beginning at the Eaton Saddle near Mount Markham and San Gabriel Peak in the San Gabriel Mountains in the Angeles National Forest, United States. Its drainage flows into the Rio Hondo river and then into the Los Angeles River. It is named after Judge Benjamin S. Eaton, who lived in the Fair Oaks Ranch House in 1865 not far from Eaton Creek.The most well-known portion of the canyon is the Eaton Canyon Nature Center in Pasadena, California. The trailhead of the Mount Wilson Toll Road is in the canyon.HistoryEaton Canyon is in the foothills of the San Gabriel Mountains. Originally called "El Precipicio" by the Spanish settlers because of its steep gorges, the canyon falls under several governmental jurisdictions.Benjamin Eaton was hired by Don Benito Wilson to bring water to the Fair Oaks Ranch. 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."On October 27, 1993, the floor of Eaton Canyon, along with 118 surrounding homes, was devastated by a wildfire.
