1959 Map of Chilao Flat

About this map

Monte Cristo Mine and several other prospecting sites like the Loomis Mine and Falcon Mine dot the high elevations of the Angeles National Forest in this late 1950s survey. The landscape is defined by its network of deep canyons and prominent peaks, including Granite Mtn and Strawberry Peak, where drainage systems like Big Tujunga Canyon and Arroyo Seco carve through the terrain. Human activity is centered on a series of specialized outposts and mountain retreats, such as Loomis Ranch, Colby Ranch, and the Newcomb Ranch. The presence of the Barley Flats Military Reservation and multiple forest service facilities like Chilao Station and Charlton Station indicates the area's dual role as a managed resource and a strategic overlook. Recreational use is well-established through numerous camps and picnic areas, including Camp Hi-Hill and Charlton Flats Picnic Grounds, all linked by the winding path of the Angeles Crest Highway.
