2024 Map of Grass Mountain

About this map

Siuslaw National Forest covers much of this coastal range landscape, where high ridgelines like Grant Ridge and Easter Ridge define the drainage basins for numerous creeks. The terrain is anchored by Grass Mtn and Lone Spring Mtn, with the southeastern portion of the map transitioning into the more level Alsea Valley. This area is shaped by a dense network of waterways, including the North Fork Alsea River and the Alsea River, which are fed by smaller streams like Hatchery Creek and Mill Creek.
