1950 Map of Robbs Peak

About this map

Eldorado National Forest dominates this mid-century topographic survey, showing a landscape defined by water management and high-country landmarks. The Rubicon River and South Fork Rubicon River carve through the northern terrain, while the Georgetown Divide Ditch and Hunsucker Ditch represent the hydraulic engineering necessary for the region's development. Local human activity is anchored by historic sites such as Uncle Toms Cabin and the Hartless Guard Sta. This era marks a time before major reservoir inundations, capturing the natural flows of Silver Creek and Tells Creek near working landscapes like Lower Bassi Ranch and Granlees Ranch. Notable high points like Robbs Peak and Deer Knob overlook the valleys, while trails such as the Ellicott Trail provide a look at the backcountry infrastructure of the California Sierras.
