About this map

Cathlamet Bay dominates this coastal landscape, where the Columbia River Estuary meets a complex network of islands and tidal channels. The northern portion of the map is defined by low-lying landforms like Miller Sands, Mott Island, and Lois Island, which are separated by deep-water passages including the North Channel and South Channel. These waterways are navigated with the aid of several maritime markers, such as the Front Range Light and Beacon Number Two.

On the southern shore, the settlements of Svensen and Svensen Junction anchor the local community near the mouth of the John Day River. This area shows a transition from the marshy riverbanks to the more elevated terrain of Fern Hill. Local heritage is preserved at the Forest Hill Cemetery, while regional infrastructure is represented by Old Highway 30 and the Karpens Airstrip. The southern interior is deeply etched by numerous drainages, including the Wallooskee River and Eskeline Creek, reflecting a landscape shaped by significant rainfall and riverine processes.
