Necanicum Junction serves as the focal point for this coastal Oregon corridor, where the modern travel routes of Us-26 and Or-53 meet. The landscape is defined by its complex drainage systems, featuring the headwaters of the Lewis and Clark River flowing north and the Necanicum River winding through the southern portion of the quadrangle. The terrain rises sharply to landmarks such as Davis Point and Twin Peaks, revealing the steep topography characteristic of the Northern Oregon Coast Range.
