2020 Map of Grass Mountain
USGS Topo · Published 2020About this map
The Siuslaw National Forest dominates this section of the Oregon Coast Range, where steep timberlands are carved by a dense network of drainages. High points like Grass Mtn and Easter Ridge provide the primary vertical relief, while the Alsea Valley in the southeast corner offers a small pocket of lower, flatter terrain near the confluence of the Alsea River. The map reveals a landscape shaped by both natural topography and administrative history, clearly marking the Lincoln Co Benton Co line as it cuts through the mountains.
