The Alsea River system serves as the central artery for this mid-1950s survey of the Coast Range, where the confluence of the North Fork Alsea River and South Fork Alsea River defines the local geography. The settlement of Alsea is the primary hub, surrounded by a landscape increasingly managed for conservation and resources, including the Corvallis Watershed and the Siuslaw National Forest. The presence of the State Fish Hatchery and the Alsea Guard Station underscores the region's focus on forest and wildlife management during this era.
