デルマーバ半島
The entire Delmarva Peninsula falls within the Atlantic Coastal Plain, a flat and sandy area with very few or no hills; the highest point in the peninsula is only above sea level. The fall line, found in the region southwest of Wilmington, Delaware, and just north of the northern edge of the Delmarva Peninsula, is a geographic borderland where the Piedmont region transitions into the coastal plain. Its Atlantic Ocean coast is formed by the Virginia Barrier Islands in the south and the Fenwick Island barrier spit in the north.
