The Lewis and Clark River and its intricate drainage network define this 1980s landscape in Clatsop County. This coastal mountain environment is characterized by the headwaters of the Necanicum River and the South Fork of the Lewis and Clark, where logging and resource extraction are evident through the network of unimproved roads and several marked Quarries. A significant portion of the southern area is dedicated to the Clatsop State Forest, showing the region's long-standing reliance on timber management and forest conservation.
