The Alsea River winds through the central valley of this Oregon coastal landscape, supporting the communities of Tidewater and Little Albany. This 2017 survey details the complex hydrography of the Siuslaw National Forest, where tributaries like Drift Creek and Canal Cr carve deep drainage patterns between prominent elevations such as Butler Peak and West Ridge. The map illustrates the contemporary settlement patterns along the river, including the Alsea Riviera development and the historical Tidewater Cem.
