Saddle Mountain and Humbug Mtn dominate the high ground of the Oregon Coast Range in this 2014 survey. This area serves as a significant drainage divide for Clatsop County, where the headwaters of the Youngs River flow north, while the Necanicum River and Little Fork Nehalem River drain to the south and west. The landscape is defined by its complex hydrology, featuring numerous named tributaries such as Destruction Cr, Beaver Cr, and Little Fishhawk Cr. Transportation through this timber-rich region is largely restricted to Us-26, which winds through the southern portion of the quadrangle, and the Fishhawk Mainline road network. Significant ridges like Flagpole Ridge provide structural definition to the watershed, illustrating the steep topography that separates the Lewis and Clark River system from the surrounding coastal basins.
