Shoreline change is a dynamic process, especially at Wasque, the southern part of Chappaquiddick, owned and managed by The Trustees of Reservations. This shoreline is very dynamic, sometimes accreting rapidly and sometimes eroding rapidly. Wasque is now eroding rapidly — parking lots have eroded away this winter, leaving an almost unrecognizable beach. What is going on? Why is it eroding so much now? There are several factors that explain this change.
