Canyons of the Colorado by J. W. Powell

their tears were gathered in brooks, and the brooks carved canyons down
the sides of the domes; and now in these deep clefts the structure of
the mountains is revealed. The lenses of volcanic rocks by which the
domes were upheaved are known as "laccolites," _i. e.,_ rock lakes.

Looking southwestward from the Henry Mountains the Circle Cliffs are
seen. A great escarpment, several thousand feet in height and 70 or 80
miles in length, faces the mountain. It is the step to the long, narrow
plateau. The streams that come down across these cliffs head in great
symmetric amphitheaters, and when first seen from above they present a
vast alignment of walled circles. The front of the cliffs, seen from
below, is everywhere imposing. On the southwest the Escalante River
holds its course. It heads in the Aquarius Plateau and flows into the
Colorado. Its course, as well as that of all its many tributaries, is in
deep box-canyons of homogeneous red sandstone, often with vertical walls
that are broken by many beautiful alcoves and glens. Much of the region
is of naked, smooth, red rock, but the alcoves and glens that break the
canyon walls are the sites of perennial springs, about which patches of
luxuriant verdure gather.

The Kaiparowits Plateau is an elevated table-land on the southwestern
side of the Escalante River. It is long and narrow, extending from the
northwest to the southeast approximately parallel with the Escalante. It
rises above the red sandstone of the Escalante region from 2,000 to
4,000 feet by a front of storm-carved cliffs. From the southeastern
extremity of this plateau, at an altitude of 7,500 feet, an instructive
view is obtained. One of the great canyons of the Colorado River can be
seen meandering its way through the red-rock landscape. In the distance,
and to the north, the Henry Mountains are in view, and below, the
canyons of the Escalante and the red-rock land are in sight. Across the
