About this map

Siuslaw National Forest covers the eastern portion of this quadrangle, where the headwaters of several key regional water systems originate along the Coast Range divide. The topography is defined by prominent summits such as Trask Mtn and Sheridan Peak, which serve as drainage points for the Nestucca River and the N Yamhill River. This 2017 survey reveals a landscape heavily managed for water resources, featuring multiple catchments including McGuire Reservoir, Walker Cr Reservoir, and the uniquely named Such Jojo Reservoir.

A complex network of timber and access roads, such as NW Bald Mtn Access Rd and Headquarters Grade, crisscrosses the terrain, linking remote points like Elk Flat and Snap Point. The map also captures the Tillamook and Yamhill county line as it traverses high ridges between Ball Bearing Hill and the deep canyons of Willamina Cr, providing a detailed view of the infrastructure supporting Oregon's coastal forests.
