DESCRIPTION OF THE COUNTRY

The Navaho reservation comprises an extensive area in the extreme
northeastern part of Arizona and the northwestern corner of New Mexico
(plate LXXXII). The total area is over 11,000 square miles, of which
about 650 square miles are in New Mexico; but it would be difficult to
find a region of equal size and with an equal population where so large
a proportion of the land is so nearly worthless. This condition has had
an important effect on the people and their arts, and especially on
their houses.

The region may be roughly characterized as a vast sandy plain, arid
in the extreme; or rather as two such plains, separated by a chain of
mountains running northwest and southeast. In the southern part of the
reservation this mountain range is known as the Choiskai mountains,
and here the top is flat and mesa-like in character, dotted with little
lakes and covered with giant pines, which in the summer give it a
park-like aspect. The general elevation of this plateau is a little less
than 9,000 feet above the sea and about 3,000 feet above the valleys or
plains east and west of it.

The continuation of the range to the northwest, separated from the
Choiskai only by a high pass, closed in winter by deep snow, is known as
the Tunicha mountains. The summit here is a sharp ridge with pronounced
slopes and is from 9,000 to 9,400 feet high. On the west there are
numerous small streams, which, rising near the summit, course down the
steep slopes and finally discharge through Canyon Chelly into the great
Chinlee valley, which is the western of the two valleys referred to
above. The eastern slope is more pronounced than the western, and its
streams are so small and insignificant that they are hardly worthy of
mention.

Still farther to the northwest, and not separated from the Tunicha
except by a drawing in or narrowing of the mountain mass, with no
depression of the summit, is another part of the same range, which bears
a separate name. It is known as the Lukachukai mountains. Here something
of the range character is lost, and the uplift becomes a confused mass,
a
