Dixie Mtn rises as a central landmark in this 1961 survey, marking a rugged intersection where Columbia, Multnomah, and Washington counties meet. The landscape is defined by the headwaters of numerous drainages, including Dutch Canyon and South Scappoose Creek flowing northeast, while McKay Creek and Rock Creek drain the southern slopes. Settlement patterns are concentrated along the ridgelines and creek valleys, characterized by a mix of agriculture and community institutions.
