About this map

The San Gabriel Mountains dominate this 1930s survey, revealing the complex drainage systems of the Angeles National Forest before extensive modern development. The confluence of the West Fork and North Fork San Gabriel River forms a central geographical anchor, surrounded by steep terrain and prominent heights like Monrovia Peak.

Evidence of early recreational and backcountry use appears through isolated outposts such as the Associated Bait Club, Stone Cabin, and Pool Cabin. These small settlements, reached via early firebreaks and trails, illustrate the canyon-dwelling culture and conservation efforts of the era. The map also delineates the intricate paths of Tujunga Canyon, Bear Canyon, and Chileno Canyon, which provide a detailed record of the natural topography used by early forest rangers and outdoor enthusiasts during the New Deal era.
