About this map

Cochran stands as a focal point within the Tillamook State Forest, situated along the Southern Pacific railroad line where it skirts the South Fork Nehalem River. This 1970s landscape is defined by the intersection of industrial transport and the drainage networks of the Salmonberry River and the Nehalem River. The map detail reveals the infrastructure of a working timberland, with borrow pits and numerous logging grades like Standard Grade and Storey Burn Road carving through the steep elevations of Salmonberry Mountain and Larch Mountain.

Tracing the proximity of Cochran Pond and the Water Tank near the railroad tracks provides insight into the steam-era requirements and later maintenance needs of this trans-mountain route. The surveyor's notes capture a high-altitude network of creeks such as Idiot Creek and Giveout Creek, illustrating the remote and specialized nomenclature of the Pacific Northwest woods during this era of heavy timber extraction.
