The Beaches are Moving - Or at Least, They Should Be
- "In principle, the islands should be migrating west. The mechanism works like this: From time to time, storms slice new inlets through the islands. Seawater rushes through, depositing sand behind them. Meanwhile, waves and wind push sand across the top of the islands. As the ocean side erodes and the sound side grows, the islands slowly roll over themselves, like a bulldozer's tread. Or at least they would if the same development that transformed the Outer Banks into a vacation wonderland hadn't jammed the machinery of island migration." - excerpt from article in National Geographic.
