A few feet further, and the cross-bedded sandstone may be seen far below on the right, out of plumb with the same mass on the left, to which it belongs, clearly showing that some convulsion of nature has either thrust the mass on the left up, or forced the mass on the right down.

From this spot a fine view is had of the red-wall limestone below and the Indian Garden; and, far below, at the end of Pipe Creek, the peculiar folding of the Algonkian strata. This folding is also to be seen on the other side of the river in the same rocks.

Trees, Flowers and Birds. While descending the first mile of trail, one sees plenty of flowers and shrubs, and many Douglas spruces. These do not exist on the rim, and, strange to say, the pines which abound there are never found on the trail. One will generally hear the sweet descending "pipe" of the canyon wren, and the harsh scolding of the blue-winged pinion jay. Hawks, owls, mocking-birds and robins are often seen. Butterflies, moths, and humming-birds wing their way to and fro and give a delicate touch of life to the stern rocky features. Time was when the visitor at El Tovar who went down the trail to the river might have seen mountain sheep, bear, deer, antelopes and coyotes.
