About this map

Eden Hot Springs sits at the base of the steep terrain overlooking Nuevo Potrero, a pocket of developed history in a landscape defined by dramatic geological formations. The northeastern corner shows the early growth of Yucaipa and Calimesa, where the Calimesa Airport and local water infrastructure supported expanding orchards and small residential tracts. Through the center of the sheet, the Southern Pacific railroad follows the natural corridor of the San Timoteo Creek through Timoteo canyon, connecting the settlement of El Casco with Nicklin further east.

Erosion and water drainage patterns dominate the western half of the map, labeled simply as The Badlands. This area is characterized by a dense network of ridges and gullies that sharply contrast with the flatter canyon floors. Features like El Casco Lake and various reservoirs highlight the constant effort to manage water in this semi-arid environment, while the Radio Relay Station on the eastern heights suggests the era's advancing telecommunications infrastructure.
