Other interesting features of the landscape are found in the great monuments and buttes that are scattered here and there, attesting to n former extension of the beds seen in the more distant clHfs. Of the cliffs more will be saiJ hereafter. Olen Canon is the channel which the Colorado River h~ts cut for itself through beds of red aud orange sandstones. Its head is at the mouth of tho Dirty Devil, and its foot at the mouth of the Paria. It terminates abruptly below by an escarpment which we have called the "Vermilion Cliffs." Along this hTegular line, extending from east to west across the Colorado, and far back on either side, the general surface of the country suddenly drops down. MARULE CANON. Tho escarpment, which we call the "Vermilion Cliffs," at the foot of Glen Canon, exposes tho same bods as are seen in the face of the Orange Cliff8, at the foot of Labyrinth Canon. It will be remembered that the beds exposed in tho Terrace Canons dip to the north. Between tho Orange Cliffs and tho Vermilion Cliffs the strata arc variously dipped by monoclinal folds, having their axes in a northerly and southerly direction, and the red beds arc at about the same altitude above the sea at the two points. The V ermilion Cliffs which face the south form a deep, re-entering angle at the ~outh of tho Paria. On tho east side of tho Colorado, the line stretches to the southeast for many miles; on the west side, it extends, in a southwesterly direction, about fifteen miles, then turns west, and, at last, to the northwest. The general northerly dip is again observed from tho mouth of the Paria to the mouth of the Colorado Chiquito. The general surface of tho country between tho two points is the summit of tho Carboniferous formation. At the mouth of tho Pari a this is at the water's edge; at the mouth of tho Colorado Chiquito it is 3 7 800 feet above the river. The fall of the river, in the same distance, is about six hundred feet, so that the whole dip of the rock between the two points is about three thousand two hundred feet. Tho distance, by river, is sixty five miles; in a direct line, twenty miles loss. So we have a dip of tho formation of 3,200 feet in forty five miles, or about seventy feet to a milo.
