About this map

The Skagit River meanders through the northern edge of this landscape, framing islands like Skiyou Island and Ross Island as it passes the established settlement of Sedro-Woolley. This mid-century survey captures a region defined by its timber and rail infrastructure, where the Northern Pacific railroad winds along the western valley, connecting the lakeside communities of Clear Lake, Big Lake, and McMurray.

Deep in the interior, the topography rises sharply toward Cultus Mtn and Table Mtn, revealing a network of logging-related infrastructure such as the Old Railroad Grade and numerous Truck Trails. To the southeast, the shoreline of Lake Cavanaugh is clearly delineated, accessible via the Lake Cavanaugh Road. The map also captures smaller locales like Montborne and Cicero, along with family-named landmarks and rural routes like Cedarvale Loop Road, providing a precise record of Skagit and Snohomish County land use before late-century development.
