The celebrated Falls of the Yellowstone (Fig. 73) consist of 
two pitches, one 140 feet, and the other a quarter of a mile below, 
where the river plunges down a distance of 350 feet, into a cañon 
whose walls are 1200 to 1500 feet high, and “decorated with the 
The Great Canon and Lower Falls of the Yellowstone. 
most beautiful colors that the human eye ever saw, with the rocks 
weathered into an almost unlimited variety of forms.” . . - It is 
a sight far more beautiful, though not so grand or impressive a$ 
that of Niagara Falls.
