About this map

Cascadia and the winding course of the South Santiam River define this portion of Linn County as documented in 2011. The settlement area, including the Cascadia Post Office, sits at the convergence of several drainages like Dobbin Creek and Cabin Creek. The landscape is notably marked by dramatic changes in elevation and hydrology, evidenced by numerous cataracts such as Upper Soda Falls, Lower Soda Falls, and Rainbow Falls.

Further north, the waters of Green Peter Lake inundate the valley, creating the Green Peter Peninsula and Whitcomb Island. For local historians and genealogists, the Whitcomb Island Cemetery remains a significant landmark near the lake's edge. The complex network of forest roads, including Canyon Creek Rd and NFD 505 Rd, provides access across the ridgelines of Moose Ridge and High Deck, illustrating the modern management of this timber-rich corridor.
