A succinct and readable account of the geological features of the Cañon will be found in the United States Geological Survey’s admirable Guide Book of the Western United States, Part C—a book of especial value to the car-window observer on the Santa Fe route. Trains to the Cañon are arranged so that travelers may reach it in the early morning and leave the same evening. In a way this is unfortunate, for it offers a temptation, almost irresistible to an American tourist, to “do” the place in a day and go on to some other sight. Of course no one _can_ do it in a day, but he can do certain things, and he can get a notion of the general scheme. Three days at least would best be planned for, and of course more still would be better. The principal features that should not be missed, may be summed up as follows: A horseback trip down into the Cañon by either Bright Angel Trail or the Hermit Trail; the drive (15 miles the round) over the Hermit Rim road; the auto trip (26 miles the round) to Grand View Point. There are, moreover, several short drives of four or five miles by public coach to vantage points along the rim, costing a dollar or two per passenger; and of course walks innumerable, among which that to Hopi Point, about 2 miles northwest from the railway terminus, is particularly to be recommended for its sunset view of the Cañon. Another pleasant short rim walk is to Yavapai Point, 1½ miles to the eastward. From both these points the view is superb. The trip down the Bright Angel[80] trail to the river and back is an all day jaunt. To the tenderfoot it is a somewhat harrowing experience to be borne downward at an angle of 45 degrees more or less on the back of a wobbling animal, whose head at times hangs over eternity, and whose only footing is on a narrow shelf scratched out of a precipitous wall of the Cañon. However, as nothing tragical happens, and as there is no escape once you are started on the _descensus Averni_, you soon find enjoyment in the novel trip, zigzagging ever downward through successive geologic ages marked by rock strata in white, red, brown and blue.
