The Alsea River snakes through the heart of the Siuslaw National Forest, anchoring a landscape defined by timber, mountain ridges, and isolated outposts in the mid-1950s. The settlement of Tidewater serves as a focal point along the river's winding course, while the confluence of Five Rivers and the Yachats River drainage to the south reveal the complex hydrology of the Coast Range. This survey, updated from 1942 planetable work and 1952 aerial photography, documents a period when forest management and local agriculture were primary drivers of the region's economy.
