of rocks, extending toward the river, 200 or 300 feet high and 600 or 800 feet long. We come back to where this sets in and find it cut off from the main wall by a great crevice. Into this we pass; and now a long, narrow rock is between us and the river. The rock itself is split longitudinally and transversely; and the rains on the surface above have run down through the crevices and gathered into channels below and then run off into the river. The crevices are usually narrow above and, by erosion of the streams, wider below, forming a network of "caves", each cave having a narrow, winding skylight up through the rocks. We wander among these corridors for an hour or two, but find no place where the rocks are broken down so that we can climb up. At last we determine to attempt a passage by a crevice, and select one which we think is wide enough to admit of the passage of our bodies and yet narrow enough to climb out by pressing our hands and feet against the walls. So we climb as men would out of a well. Bradley climbs first; I hand him the barometer, then climb over his head and he hands me the barometer. So we pass each other alternately until we emerge from the fissure, out on the summit of the rock. And what a world of grandeur is spread before us! Below is the canyon through which the Colorado runs. We can trace its course for miles, and at points catch glimpses of the river. From the northwest comes the Green in a narrow winding gorge. From the northeast comes the Grand, through a canyon that seems bottomless from where we stand. Away to the west are lines of cliffs and ledges of rock--not such ledges as the reader may have seen where the quarryman splits his blocks, but ledges from which the gods might quarry mountains that, rolled out on the plain below, would stand a lofty range; and not such cliffs as the reader may have seen where the swallow builds its nest, but cliffs where the soaring eagle is lost to view ere he reaches the summit. Between us and the distant cliffs are the strangely carved and pinnacled rocks of the Toom'pin wunear' Tuweap'. On the summit of the opposite wall of the canyon are rock forms that we do not understand. Away to the east a group of eruptive mountains are seen--the Sierra La Sal, which we first saw two days ago through the canyon of the Grand. Their slopes are covered with pines, and deep gulches are flanked with great crags, and snow fields are seen near the summits. So the moun- FROM THE GRAND TO THE LITTLE COLORADO. 213 tains are in uniform,--green, gray, and silver. Wherever we look there is but a wilderness of rocks,--deep gorges where the rivers are lost below cliffs and towers and pinnacles, and ten thousand strangely carved forms in every direction, and beyond them mountains blending with the clouds.
