2024 Map of Tiernan
USGS Topo · Published 2024About this map
The Siuslaw River corridor and its tidal influence dominate this portion of Lane County, where the southern valley contains the small riverside settlements of Tiernan and Point Terrace. This modern survey illustrates the complex drainage system of the Siuslaw National Forest, where steep coastal ridges like Misery Ridge and Hanson Ridge overlook a network of tributary creeks. The presence of Duncan Inlet and Sweet Creek near the main river channel indicates the transition from upland forestry to the estuarine environment of the Oregon coast.
