Many
cities in the eastern
United States are located along a geographical feature known as the
Fall Line. The fall line marks the area where the upland region of the
Piedmont meets the Atlantic
Coastal Plain. The fall line is typically prominent where a river crosses it, for there will usually be rapids or waterfalls. Since these features frequently mark the
head of navigation and supply ample
water power, river port settlements and early manufacturing settlements often developed along this line. Many of these settlements are now major American cities.
