1955 Map of Concrete
USGS Topo · Published 1967About this map
Ross Lake and Lake Chelan dominate the interior of this mid-century survey, which reveals the complex hydrology and geography of the North Cascade Range before the full impact of modern development. Along the Skagit River corridor, small settlements like Concrete and Rockport serve as gateway hubs for the regional timber and hydroelectric interests. Further south, the Great Northern railway skirts the western edge of the mountains, connecting Granite Falls and Robe to the industrial centers of the coast.
