About this map

Monte Cristo Mine and a cluster of nearby workings including the Falcon Mine and Gold Bar Mine define the mid-century industrial footprint within these high reaches of the Angeles National Forest. The landscape is a network of canyons and peaks, with the Angeles Crest Highway (noted as Highway 2) providing the primary artery through the region. Small enclaves of private and public use are scattered throughout, from the remote Loomis Ranch with its small cemetery to established waypoints like Newcomb Ranch and Colby Ranch.

Resource management and recreation are central to the 1950s character of the area, evidenced by the Barley Flats Military Reservation and numerous forest stations such as Chilao Station and Red Box Station. Organized camps, including Camp Hi-Hill and Camp Rosenita, highlight the era's transition toward recreational forest use, while features like Big Tujunga Canyon and the West Fork San Gabriel River anchor the drainage systems that shaped the early settlement patterns of the Los Angeles mountains.
