East Fork Road, located in the San Gabriel Mountains above the city of Azusa, California, is a road that gives access from State Route 39 into East Fork and other small townships, including Camp Williams and Julius Klein Conservation Fire Camp 19, a minor offender prisoner housing complex where "LACO fire personnel provide training, which prepares inmates to safely conduct wild land firefighting operations.
The terminus is Heaton Flats, which has a campsite, a toilet facility, and trails that lead upstream and to the summit of Iron Mountain, 8,007 feet (2,441 m) above.
Along East Fork Road there are extensive fire-fighting facilities which are staged to combat the many fires that break out among the foothills above Azusa, Glendora, and San Dimas every year.
The United States Forest Service states that all mining operations, including gold panning, are illegal along the East Fork;[2] Additionally, since the area’s designation as a National Monument in 2014, all resource extraction is prohibited (as is the case on all National Monuments).
Sections of destroyed bridge supports give hikers clues as to where the roadway used to be located; however, extensive sections of the asphalt-covered road still exist and lead up to Laurel Gulch and the John Seals Bridge, which is located just before one enters the Sheep Mountain Wilderness.
