The exact number of rapids cannot be given, as in some portions of Lodore, 
Cataract, Marble, and the Grand Canyon it is difficult to divide the almost con¬ 
tinuous fall into parts. The number also varies with the stage of water, a high 
stage covering up some of the smaller rapids. I count 62 rapids in Cataract Can¬ 
yon, but Stanton makes it 75. The discrepancy arises in the way of dividing 
some of the descent in the worst portions. Lodore for a large part of its length is 
so nearly one continuous rapid that it is difficult to count the special drops. In 
Marble Canyon I counted 73, and in the distance from the Little Colorado to the 
mouth of the Kanab, 131. We counted about 600 from Green River Valley to 
the Kanab Canyon, and Stanton’s party counted 520 large rapids from Fremont
