Chappaquidick, the easternmost natural appendage of Martha’s Vineyard, suggests a small replica of the larger land mass: an island of upland woods, coastal heath, protected bays, and barrier beaches. However Wasque is at the epicenter of dynamic coastal change which is all part of a cycle of natural barrier beach openings which help cleanse Edgartown Harbor of layers of built-up silt and mud and replaces it with sand. This flushing of Edgartown Harbor is expected to bring a boon to the area’s recreational and commercial shellfisheries and provides new opportunities for shore anglers.
