About this map

The South Fork Santiam River carves through this mid-1980s landscape, serving as the central artery for the small community of Cascadia. The settlement is closely tied to the surrounding Cascadia State Park, where the convergence of Soda Creek and the river highlights a long history of water-centric activity, including the documented Soda Spring. Further north, the expansive Green Peter Lake dominates the terrain, creating complex shorelines around the Peninsula and Whitcomb Island.

Industry and recreation intersect throughout the Willamette National Forest, with Quartzville Road providing access to Quartzville Park. The map documents several natural landmarks including Upper Soda Falls, Lower Soda Falls, and Rainbow Falls, alongside resource extraction sites like a Quarry and Gravel Pit. The rugged elevation of Moose Ridge and High Deck illustrates the steep Cascades foothills terrain that has historically shaped timber and transit routes in Linn County.
