About this map

Stanislaus National Forest terrain dominates this 1940s topography, showing a landscape defined by the deep canyons of the Stanislaus River and its multiple forks. Significant industrial and utility infrastructure is evident, including the Utica Ditch system, a prominent Powerhouse, and a Tunnel cutting through the ridges. Small mountain settlements such as Avery and Hathaway Pines are located along the Ebbetts Pass Highway, providing a look at the early residential and commercial footprint in this part of Calaveras and Tuolumne Counties.

The map's detail reveals the importance of forest management and early resource extraction, marked by the Calaveras Ranger Sta, the Lumber RR near Long Canyon, and strategically placed fire watch points like the Forebay Lookout and McCormick Lookout. Water management is further illustrated by the Hunter Reservoir and Forebay, supporting the region's hydro-electric and irrigation needs before later mid-century expansions.
