The Siuslaw National Forest dominates the southern landscape of this Tillamook County interior, where the high divide at Trask Summit separates major drainage systems. In the northern sections, the South Trask River and the E Fork Trask River carve through the terrain, while the Nestucca River and Testament Cr define the southern waterways. The map documents a complex network of forest access and logging infrastructure, including Murphy Camp Rd and Headquarters Camp Rd, reflecting the area's history of timber management. Named elevations like Dovre Peak and Simmons Ridge overlook numerous small tributaries such as Bear Cr, Tucca Cr, and Elk Cr. This survey illustrates the geographic transition between the Trask and Nestucca river basins within the protected forest boundaries.
