July 14.-This morning, we pass some curious black bluffs on the right, then two or three short canons, and then we discover the mouth of the San Rafael a stream which comes down from the distant mountains in the west. Here w' e stop for an hour or two, and take a short walk up the valley, and find it is a frequent resort for Indians. Arrow heads are scattered about, many of them very beautiful. Flint chips are seen strewn over the ground in great profusion, and the trails are well worn. Starting after dinner, we pass some beautiful buttes on the left, many of which are very symmetrical. They are chiefly composed of gypsum of many hues, from light gray to slate color; then pink, purple, and brown beds. Now, wo enter another canon. Gradually the walls rise higher and higher as we proceed, and the summit of the canon is formed of the same beds of orange colored sandstone. Back from the brink, the hollows of the plateau are filled with sands disintegrated from these orange beds. They are of rich cream color, shaded into maroon, everywhere destitute of vegetation, and drifted into long, wave like ridges. The course of the river is tortuous, and it nearly doubles upon itself many times. The water is quiet, and constant rowing is necessary to make much headway. Sometimes, there is a narrow flood plain between the river and the wall, on one side or the other. Where these long, gentle curves are found, the river washes the very foot of the outer wall. A long peninsula of willow bordered meadow projects within the curve, and the talus,. at the foot of the cliff, is usually covered with dwmf oaks. The orange colored sandstone is very homogeneous in structure, and tlie walls are usually vertical, though not very high. Where the river sweeps around a curve under .a cliff, a vast hollow dome may be seen, with many caves and deep alcoves, that are greatly admired by the members of the party, as we go by. We camp at night on the left bank. July 15.-. Our camp is in a great bend of the canon. The perimeter of the curve IS to the west, and we are on the east side of the ri vcr. Just opposite, a little stream comes down through a narrow side canon. '\V 0 cross, • TRIN-ALOOVE BEND. 53 and go up to explore it. Just at its mouth, another lateral canon enters, in the angle between the former and the main canon above. Still another enters in the angle between the canon below and the side canon first mentioned, so that three side canons enter at the same point. These canons are very tortuous, almost closed in from view, and, seen from the opposite side of the river, they appear like three alcoves; and we name this TrinAlcove Bend. Going up the little stream, in the central cove, we pass between high walls of sandstone, and wind about in glens. Springs gush from the rocks at the foot Qf the walJs; narrow passages in the rocks are threaded, caves are entered, and many side canons are observed. The right cove is a narrow, winding gorge, with overhanging walls, almost shutting out the light. The left is an amphitheater, turning spirally up, with overhanging shelves. A series of basins, filled with water, are seen at-different altitudes, as we pass up ; huge rocks are piled below on the right, and overhead there is an arched ceiling. After exploring these alcoves, we recross the river, and climb the rounded rocks on the point of the bend. In every direction, as far as we are able to see, naked rocks appear. Buttes are scattered on the landscape, here rounded into cones, there buttressed, columned, and carved in quaint shapes, with deep alcoves and sunken recesses. All about us are basins, excavated in the soft sandstones; and these have been filled by the late rains. Over the rounded rocks and water pockets we look off on a fine stretch of river, and beyond are naked rocks and beautiful buttes to the Azure Cliffs, and beyond these, and above them, the Brown Cliffs, and still beyond, mountain peaks ; and clouds piled Qver all. On we go, after dinner, with quiet water, still compelled to row, in order to make fair progress. The canon is yet very tortuous. About six miles below noon camp, we go around a great bend to the right, five miles in length, and come back to a point within a quarter of a mile of where we started. Then we sweep around another great bend to the left, making a circuit of nine miles, and come back to a point within six hundred yards of the beginning of the bend. In the two circuits, we . |
