In his book "Mountains of the Heart" (Fulcrum Publishing, 1994), Scott Weidensaul, a naturalist, maintains that the Appalachian Mountains extend from Cheaha Mountain, Alabama, to tiny Belle Isle, fifteen miles offshore in the frigid waters between Newfoundland and Labrador (not to be confused with Bell Island, near St. Johns).
Can anyone envision the AT's ever being extended to reach the extreme southern and northern ends of the mountains?
