Huxley Terrace. Huxley Terrace is the center plateau. At its end is an eroded mass of red sandstone, to which the name of the noted naturalist and evolutionist, Wallace, has been attached. Still nearer the end, and belonging to the marble wall, is a pagoda named Tyndall Dome.
Spencer Terrace. Spencer Terrace is the most western of the plateaus, and is where the Mystic Spring used to be, which for many years gave its name to Bass's Trail--the Mystic Spring Trail.
These three plateaus vary in width from a quarter of a mile to over a mile wide; they are dotted with what seem to be patches of grass, but which in reality are juniper and pinion trees from ten to forty feet in height.
Terraces of the Explorers. About a quarter of a mile to the west of Bass Camp is the amphitheatre in which my earlier book, "In and Around the Grand Canyon," and a large part of the present book were written. From this restful spot I have looked out thousands of times across the great bend of the river and Garnet Canyon to the five terraces named after the early-day Spanish explorers, Marcos, De Vaca, Tovar, Alarcon, and Garces.
Points of the Explorers. To the west stands out Chemehuevi Point, six thousand six hundred and twenty-six feet, while across the river, terminating Powell Plateau, are Wheeler Point, six thousand seven hundred and fifty feet, and just beyond it Ives Point, six thousand six hundred feet.
To the north of Ives Point, but hidden from view, are Beale Point, six thousand six hundred and ninety-five feet, Thompson Point, six thousand seven hundred and thirty feet, and Newberry Point, six thousand seven hundred and fifty feet, all named after early Arizona explorers and geologists.
Conquistadore Aisle and Steamboat Mountain. The dark chasm of the river itself, where it moves almost due west, has been named Conquistadore Aisle, in honor of the men whose names are attached to the terraces above. Here the river again curves, and its course is seen to be to the northeast, as if doubling behind Powell Plateau. It then turns back upon itself, and goes to the southwest. If the conditions are favorable, one may see, to the left of Ives Point, a majestic butte, detached from the further wall of the Canyon, and generally known as Steamboat Mountain. It is an object of great interest, when seen from the saddle on the north rim by those who have crossed the Canyon and are journeying to Point Sublime.
The Scenic Divide. Now let the observer compare the view to the left with that which he has carefully examined on the right. There, in the latter view, are towers and buttes, detached monuments, and a perfect bewilderment of scenic features; here, to the left, save for the aisles, terraces and further wall, there is little to attract attention. The view, comparatively, is uninteresting. The reason for this is clear. The granite of the Inner Gorge has disappeared. Here is the Scenic Divide, the natural line of demarcation between two distinctive portions of the Canyon, the scenery of which is markedly diverse. Where the granite is in evidence, the stratified rocks resting upon it are carved into varied forms: Where the river flows through the stratified rocks, and no granite appears, there are few or no buttes, no towers, no monuments. Nowhere else, in the accessible portions of the Canyon, is this difference seen, for at Grand View, the head of the old Hance Trail, the Red Canyon Trail, Boucher's and the Bright Angel Trails, the outlooks are over areas where the granite has thrust itself out of the bowels of the earth.
Bass's Cable Crossing. The ride down Bass's Trail is an interesting one, passing on the way two prehistoric water-pockets and several cliff-dwellings. On the plateau below, forty miles of trail riding, almost on the level, may be indulged in, before one descends the narrow Canyon to Bed Rock Camp and the river. Here a ferry and cable crossing have been established, the former for use during low water, while, after the flood season begins, the latter enables travelers and stock to make a safe passage in the cage suspended from the cable.
