Saddle Mountain and Humbug Mountain anchor this high-elevation terrain in Clatsop County, where the headwaters of several major Oregon coastal rivers originate. The landscape is defined by its drainage systems, notably the Lewis and Clark River flowing northwest and the Youngs River and its South Fork moving north. In the southern portion of the map, the Necanicum River and the Little North Fork Nehalem River trace significant east-west corridors. Access is facilitated by the Saddle Mountain Rd leading into Saddle Mountain State Park. This topography reveals a complex network of creeks like West Humbug Creek and Beaver Creek, highlighting the importance of timber and watershed management in the Coast Range at the start of the 2010s.
