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 continuous 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 Canyon. 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 63, 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 River to the Grand Wash, or about 600 from the Junction.
From Green River Valley to the foot of Black Canyon something over 1000
would be a near estimate of the total number of rapids. The velocity
is always tremendous. The width of the river varies according to the
locality. Green River is from 250 to 400 feet in the canyons, and 800
to 1000 in the valleys. The Colorado is from 75 to 400 or 500 in the
canyons and from 1200 to 1500 in the valleys. In the Granite Gorges
there are points where the distance between the buttresses at the water
is no more than 50 feet. In Marble Canyon there are a dozen places where
the width is not over 60 to 75 feet. The depth varies from several feet
to an unknown quantity in the narrow parts. There is also a variation
of depth with the year and the season. Years when the high mountains
receive an abnormal snow-fall the river rises to abnormal heights and
at such times the depth of water in the Grand Canyon is enormous and the
velocity appalling. Ordinarily the current varies from three miles per
hour to twenty or mere.

Our method of navigating was to go with caution. A landing was made
above every rapid where possible, and the rapid inspected. Sticks were
thrown in when practicable and watched to find the set of the main
current which w
