1963 Map of Ross Dam

About this map

Ross Dam serves as the focal point of this northern Washington landscape, holding back the waters of Ross Lake where it meets the Skagit River. This 1963 field-checked survey illustrates a complex hydraulic and recreational network at the intersection of North Cascades National Park and the Ross Lake National Recreation Area. Near the dam, the Powerhouse and Ross Lake Guard Station represent the administrative and industrial presence in the canyon, while Diablo Lake Resort and Buster Brown Flats indicate the established visitor footprint along Diablo Lake. High-altitude features like the Sourdough Lookout and Neve Glacier contrast with the deep-water arms of the reservoirs. The map documents an intricate trail system, including the Happy Creek Trail and Thunder Creek Trail, which navigate the steep drainages of Horsefly Creek and Lillian Creek toward remote landmarks like the John Pierce Waterfall.
