1947 Map of Jawbone Ridge

About this map

Stanislaus National Forest land dominates this 1940s landscape, revealing a complex network of resource management and early Sierra tourism. The infrastructure of the Hetch Hetchy Aqueduct (South Channel) and the Hetch Hetchy Trail cut across the central terrain, marking the vital water-conveyance systems serving distant urban centers. Small outposts and service points like Smith Station and the Groveland Ranger Sta indicate the administrative and travel-related hubs of the era, while the Gold Queen Mine (Abandoned) and Argo Mine point to an earlier era of mineral extraction that shaped the local geography.
