National Forests of California 1931, prepared by the U.S. Department of Agriculture's Forest Service for the California region in 1932, provides an insightful cartographic representation of the national forests, main traveled roads, and national highways of the state. The map presents not only a spatial understanding of California's prized natural reserves but also sheds light on the infrastructure developments that were connecting and traversing these ecological treasures.
The early 1930s marked an era of conservation consciousness in the United States, particularly in the wake of the establishment of numerous national parks and forests. In California, the juxtaposition of the state's bustling urban centers and its vast, pristine wilderness areas was becoming more pronounced, making it vital for both residents and visitors to understand the geography of these protected spaces. This map, by delineating national forests, traveled routes, and major highways, emphasizes the accessibility and interconnectivity of these wild areas to the state's urban centers.
One of the standout features of this map is the photographically illustrated title cartouche situated in the upper right, blending the precision of cartographic design with the artistry of early 20th-century photography. The topography is meticulously represented with shading techniques, highlighting the varied terrains and emphasizing the rich biodiversity of the Californian forests.
On the reverse side of the map, extensive essays delve deeper into subjects pertinent to the national forests and their relevance, accompanied by further photographic illustrations. These essays serve as an informative companion to the map, enriching one's understanding of California's forested regions and the nation's commitment to conservation during this period.
