The Whaleback Shell Midden is a historic site and park in Damariscotta, Maine. It is a very interesting site telling of the ancient Native American cultures that once lived in the area.

The Whaleback Shell Midden is basically a shell midden or dump. It was made mostly of oyster shells that were found on the Damariscotta River. Experts believe that the middens were created through a course of a thousand years more than two thousand years ago. It got its name from its shape that appears like the back of a whale.

Sadly, the Whaleback Shell Midden has been damaged and altered largely in the late 1880s when the shell heap was used for making chicken feed. Visitors of the site can still get a good view of the area today, though.
