Nicolai Mountain and Nicolai Ridge dominate this section of the Northern Oregon Coast Range, where the landscape is defined by its drainage basins and historical timber access. The map reveals an intricate network of logging infrastructure, including the Foster Mainline, Big Creek Mainline, and the Nicolai-Beneke Grade, illustrating how the terrain was navigated for industrial use. Hydrological features are prominent throughout, from the Gnat Creek Falls on Gnat Cr to the high-elevation Lost Lake and the various forks of Plympton Cr. The southern portion of the quadrangle descends toward the Nehalem Valley, with small tributaries like Cow Cr and Walker Cr carving through the ridges. This 2014 survey serves as a record of modern forest management and topography in Clatsop County before any subsequent changes in the road systems or waterway classifications.
