A view of Plum Island, Sandy Hook. This gives you an idea of what an aerial view of Sandy Hook would look like, a compound, recurved spit. Like Sandy Hook, this small "parasitic" spit on the bay side of Sandy Hook grew in stages.

The north side of Plum Island. Notice how much of the sand on a beach is actually below the waterline.

(Bottom left and right) A good example of an erosional scarp that forms on the beach after storms and during the winter.
