Consider the Allegheny Mountains as they presented to an early 19th century pioneer with a pack mule, a horse, and perhaps a wife and a child: he does not know from escarpments; he looks at the Front and sees a Wall. Considered as a Wall that is the biggest, most formidable Wall he or any other pedestrian had ever seen: 180 miles long, 790 feet high at its lowest point to 4,770 feet at its highest.
Very un-pedestrian mountains to a 19th century pedestrian. No "easy access."
