1989 Map of Lake Shannon

USGS Topo · Published 1989

About this map

Lake Shannon dominates the northern landscape of this Skagit County region, held back by the engineering of the Baker Dam. This 1980s survey documents the area's transition into a recreational and conservation-focused corridor, centered on the Skagit Wild and Scenic River as it flows past the town of Concrete. The map illustrates the industrial footprint remaining in the valley, including a Gravel Pit and Quarry, which coexist with the protected wilderness of the Mt Baker National Forest. To the east, the settlement of VanHorn and the former location of Sauk (Site) sit along the riverbanks, providing a record of habitation patterns before modern conservation designations. High-elevation features like Jackman Ridge and the Thunder Lakes emphasize the verticality of the terrain surrounding the lower river valley.
