answer:There isn’t much variation in altitude in the Barrens. The range is a few feet above sea level to it’s highest point, Apple Pie Hill. at 208 ft, which is enough for the possibility of a 200 ft. cliff due to, let’s say, erosion. It’s believable that something like this could have happened without anyone noticing upon landfall of Hurricane Sandy. LOL. It’s a pretty barren place. Otherwise, I would suggest that you scan the topographic maps available on the net for the type of geologic characteristics you need for the story. Satellite photos are helpful also. Everything you need is on the net. Haven’t seen you around much in the past few years, Scotty. Nice to see you here again.
