2017 Map of Cochran

About this map

Cochran sits along the dividing line of Washington and Tillamook counties, serving as a focal point for the complex drainage systems of the Northern Oregon Coast Range. This high-altitude landscape is defined by the headwaters of the Salmonberry River and the S Fork Nehalem River, which carve through steep terrain marked by Giveout Mtn and Larch Mtn. The map reveals a sophisticated network of historical timber-industry access routes, most notably the Standard Grade and Beaver Slide Rd, which reflect the area's logging heritage. To the east, the terrain descends toward the Gales Creek drainage via Raven's Ridge, while the central portion is home to Cochran Pond. The density of named creeks, including Kinney Creek and Derby Creek, underscores the heavy rainfall and hydrological importance of this forested divide.
