1959 Map of Chilao Flat

USGS Topo · Published 1970

About this map

Mining and forestry operations define this mid-century view of the high country, where the Monte Cristo Mine and Falcon Mine sit amidst the steep drainage of the San Gabriel River. The landscape is a network of fire protection and recreation, evidenced by the Vetter Mountain Lookout and numerous facilities like the Chilao Station and Red Box Station. Large family-named holdings such as Loomis Ranch, which includes a private Cem, and Colby Ranch represent the historic settlement of these canyons before the expansion of the modern Angeles Crest Highway.
