About this map

Cascadia serves as a central point along the South Santiam River in this modern topographic study of the western Cascades. The landscape is defined by the significant footprint of the Willamette National Forest and the northern presence of Green Peter Lake, where Green Peter Peninsula and Whitcomb Island provide distinct topographical landmarks. Genealogists and local historians can locate the Whitcomb Island Cem on the island's western edge, a site preserved amidst the waters of the reservoir.

The map details an intricate network of forest roads like Moose Mountain Rd and Quartzville Dr that navigate the steep terrain of the High Deck and Moose Ridge. Numerous water features, including Upper Soda Falls, Lower Soda Falls, and Rainbow Falls, indicate the sharp elevation changes common in this drainage basin. Garland Bridge provides a vital crossing of the S Santiam River near the town, anchoring the local transportation corridor.
