the clouds of heaven. Mount Taylor, which stands over the divide on the
drainage of the Rio Grande del Norte, is one of the most imposing of the
dead volcanoes of this region. Still later eruptions of lava are found
here and there, and in the present valleys and canyons sheets of black
basalt are often found. These are known as coulees, and sometimes from
these coulees cinder cones arise.

This valley of the Little Colorado is also the site of many ruins, and
the villages or towns found in such profusion were of mueh larger size
than those on the San Francisco Plateau. Some of the pueblo-building
peoples yet remain. The Zuni Indians still occupy their homes, and they
prove to be a most interesting people. They have cultivated the soil
from time immemorial. They build their houses of stone and line them
with plaster; and they have many interesting arts, being skilled potters
and deft weavers. The seasons are about equally divided between labor,
worship, and play.

A hundred miles to the northwest of the Zuni pueblo are the seven
pueblos of Tusayan: Oraibi, Shumopavi, Shupaulovi, Mashongnavi,
Sichumovi, Walpi, and llano. These towns are built on high cliffs. The
people speak a language radically different from that of the Zuni, but,
with the exception of that of the inhabitants of Hano, closely allied to
that of the Utes. The people of Hano are Tewans, whose ancestors moved
from the Rio Grande to Tusayan during the great Pueblo revolt against
Spanish authority in 1680-96.

Between the Little Colorado and the Rio San Juan there is a vast system
of plateaus, mesas, and buttes, volcanic mountains, volcanic cones, and
volcanic cinder cones. Some of the plateaus are forest-clad and have
perennial waters and are gemmed with lakelets. The mesas are sometimes
treeless, but are often covered with low, straggling, gnarled cedars and
pifions, trees that are intermediate in size between the bushes of sage
in the desert and the forest trees of the elevated regions. On the
western margin of this district the great Navajo Mountain stands, on the
brink of Glen Canyon, and from its summit many of the stupendous gorges
of the Colorado River can be seen. Central in the region stand the
Carrizo Mountains, the Lukachukai Mountains, the Tunitcha Mountains, and
the Chusca Mountains, which in fact constitute one system, extending
from north to south in the order named. These are really plateaus
crowned with volcanic peaks.
