1935 Map of Alder Creek

USGS Topo · Published 1935

About this map

The San Gabriel Mountains dominate this 1935 advance sheet, reflecting a landscape defined by steep drainages and early twentieth-century activity within the Angeles National Forest. Mining history is preserved in labels for the Falcon Mine and the Monte Cristo Mine, situated among high peaks like Pacifico Mtn and Granite Mtn. The map documents early mountain outposts such as Loomis Ranch and the Chilao R S, alongside numerous water sources like Fountainhead Spring and Sheep Camp Spring. The intricate drainage network of the Big Tujunga Creek and the Middle Fork of Alder Creek illustrates the complex hydrology of the range before modern development altered much of the surrounding Los Angeles basin.
