The demand from scientists and
tourists for an accurate and detailed
map of the famous canyon of the
Colardo in Arizona has led to a re-
survey of this unique region by the
United States geological survey, under
the charge of Francois E. Murthes,
topographer The Grand canyon, for
merly reached only by stage route
over a desert country, has recently
been made accessible by branch line
of the Santa Fe route from Williams,
and during the one year that this road
has been in operation the canyon has
been visited by thousands of tourists.
In grandeur of it's scenic attractions
the canyon bids fair to rival both the
Yellowstone park and the Yosemite
valley.
The lifted States geological survey
expects to publish a series of atlas
sheets covering the entire extent of
the Grand canyon proper and consider
able areas of the high plateaus on
either side. The first of these sheets
to be known as the Bright Angel, is
nearly completed and will be available
to the public some tine next summer.
1t includes almost all of the scenery
visible from the Bright Angel hotel,
familiar to every visitor. The Colora-
do river traverse from east to west
the quadrangle represented by this
sheet and divides it almost symmetri-
cally. The new map will be on
scale of one mile to the inch and the
contour interval will be fifty feet. 1t
will show every pinnacle, spur and
gully in it's true proportions, and each
line of cliffs and terrace may be traced
along the canyon walls.
The dimensions of the Grand canyon
have been the subject of much discus
sion ever since it was first explored.
It may, therefore, be of interest to
give some figures taken from this new
survey. The average width from rim
to rim does not exceed ten miles
throughout the Kaibab, or widest sec
ton of the canyon, and frequently
narrows down to eight miles. The
river does not occupy the middle OF
the gigantic trough, but flows at
distance varying from one to three
miles from the south side, practically
all of the magnifcently sculptdred pin
nacles and mesas (the so-called tenn
ples) lie north of the river, and at
distances of from Eve to seven miles
from the viewpoint usually visited by
tourists. The depth of the Grand
canyon, in one way, has been over
stated, in another way, understated
Measured from the south rim the total
depth is considerably less than mile.
From the rim at he Bright Angel ho-
tel, where the altitude is $3.50 feet
above the sea level to the foot of the
tourist trail, the drop is 4,43O' feet.
The highest point on the south rim at
the Grand View hotel is 1896 feet,
about 1900 feet above the river. From
the north side, however, the drop to
the water level averages considerably
over mile, and in many places even
exceeds 5000 feet. 1t may be stated
in general way that the north rim
is from 1000 to 1000 feet higher than
the south, thus producing that high,
even skyline so striking in all views
obtalnable by the tourist The figures
are based on spirit levels run in con-
nection with the map work. They are
the first that have ever been run to
the bottom of the chasm, and t,.e high
standard Of accuracy maintained
throughout will cause them to be con-
sidered authoritative and final
