Some of us go out for half a mile and climb a butte to the north. The course of the Dirty Devil River can be traced for many miles. It comes down through a very narrow canyon, and beyond it, to the southwest, there is a long line of cliffs, with a broad terrace, or bench, between it and the brink of the canyon, and beyond these cliffs is situated the range of mountains seen as we came down Narrow Canyon. Looking up the Colorado, the chasm through which it runs can be seen, but we cannot see down to its waters. The whole country is a region of naked rock of many colors, with cliffs and buttes about us and towering mountains in the distance. July 29.--We enter a canyon to-day, with low, red walls. A short distance below its head we discover the ruins of an old building on the left wall. There is a narrow plain between the river and the wall just here, and on the brink of a rock 200 feet high stands this old house. Its walls are of stone, laid in mortar with much regularity. It was probably built three stories high; the lower story is yet almost intact; the second is much broken down, and scarcely anything is left of the third. Great quantities of flint chips are found on the rocks near by, and many arrowheads, some perfect, others broken; and fragments of pottery are strewn about in great profusion. On the face of the cliff, under the building and along down the river for 200 or 300 yards, there are many etchings. Two hours are given to the examination of these interesting ruins; then we run down fifteen miles farther, and discover another group. The principal building was situated on the summit of the hill. 228 CANYONS OF THE COLORADO. A part of the walls are standing, to the height of eight or ten feet, and the mortar yet remains in some places. The house was in the shape of an L, with five rooms on the ground floor,--one in the angle and two in each extension. In the space in the angle there is a deep excavation. From what we know of the people in the Province of Tusayan, who are, doubtless, of the same race as the former inhabitants of these ruins, we conclude that this was a kiva, or underground chamber in which their religious ceremonies were performed. We leave these ruins and run down two or three miles and go into camp about mid-afternoon. And now I climb the wall and go out into the back country for a walk. The sandstone through which the canyon is cut is red and homogeneous, being the same as that through which Labyrinth Canyon runs. The smooth, naked rock stretches out on either side of the river for many miles, but curiously carved mounds and cones are scattered everywhere and deep holes are worn out. Many of these pockets are filled with water. In one of these holes or wells, 20 feet deep, I find a tree growing. The excavation is so narrow that I can step from its brink to a limb on the tree and descend to the bottom of the well down a growing ladder. Many of these pockets powell-canyons-149.jpg
