GREAT FALLS OF THE POTOMAC: NEAR WASHINGTON, D. C. 



The Potomac is the best example of the short rivers of the Atlantic watershed which rise in the 

 plateau region, flow across the ridges and valleys of the stratified belt, and then burst their rock strewn 

 path through the crystalline belt to the sea. The Great Falls of the Potomac are to be the terminus of 

 a fifteen mile Riverside Drive from the nation's Capitol. The series of rapids is about a mile in length 

 and includes this splendid 35-foot cataract.
