About this map

Southern Pacific rail lines wind through the high timber of the Tillamook State Forest in this late 1970s survey. The landscape is defined by the headwaters of several major drainages, including the Salmonberry River and the South Fork Nehalem River. At the junction of the railroad and the forest boundary lies Cochran Pond, accompanied by a Water Tank, marking a critical logistical point in the rail-and-timber operations of the era.

The topography is accessed by a network of logging roads and former grades, such as the Standard Grade and Storey Burn Road. The map documents the boundary between Tillamook and Washington counties as it traverses peaks like Giveout Mountain and Larch Mountain. This record is particularly valuable for tracing the legacy of the historic rail corridor as it navigated the steep canyons of Wolf Creek and Idiot Creek before the eventual dismantling of these industrial arteries.
