My first instinct was to go, "NUH UH!!!" because some mountains *are* right on the waterline... or rather, they fade into (grow from?) Cliffs that are on the waterline, but...
When I looked at the map, it did look a little... off.
I think it's cause these are full-out mountains... not mountain cliffs.. and I've never seen them than close to shore. (Unless someone from Virginia wants to contradict me?
) Most of the ones I've seen that aren't cliffs turn into hills, and valleys/plains/flat-land-type-areas, and THEN coastlines... so you'd need to fit a couple of things in between, yes?
