After Sandy, not all sand dunes are created equal
When Superstorm Sandy hit Island Beach State Park — one of the last remnants of New Jersey's barrier island ecosystem — it flattened the dunes, pushing all that sand hundreds of feet inland.
Three months later, the park was still officially closed, but the beach swarmed with volunteers.
