About this map

Ross Lake dominates the central corridor of this survey, where the Skagit River transitions into the impounded waters of the Ross Lake National Recreation Area. The map provides a detailed view of the water's edge at a spillway elevation of 1604 feet, noting distinct landforms like Tenmile Island and Little Jerusalem Island that emerge from the reservoir. To the west, the high peaks of North Cascades National Park harbor alpine features like Skymo Lake and Sourdough Lake, while the eastern shore is defined by the Pasayten Wilderness. Local history researchers can identify established backcountry infrastructure of the era, including the Gaging Station near Big Beaver Campground and the network of primitive routes such as the East Bank Pack Trail and Big Beaver Trail that connected these remote mountain basins.
