Hike north on the Appalachian Trail and the scenery slowly transforms. Rugged, steep ridgelines in Tennessee and Virginia soften into the broad summits and smooth peaks of Pennsylvania and New Jersey. According to new research from William & Mary Assistant Professor of Geology Joanmarie Del Vecchio, this contrast speaks to an ancient past.

Not my knowledge base at all, but interesting read.

But why then are the northern parts of the same range sooo much more jagged and sharp then? (Greens, whites, Maine). If anying northern Va through Ct is very flat compared to both the north and south Appalachian.
