A hundred yards or so below where the springs commence to flow Wallapai Canyon enters from the left. It is similar in appearance to, though narrower than, Havasu (Cataract) Canyon, the walls being of red sandstone, the strata of which are as regular as if laid by masons. A few hundred yards beyond the junction of the two canyons a remarkable piece of Indian engineering is in evidence, showing how the Indians ascend from a lower to an upper platform. There is a drop here in the stratum of some twenty-five or thirty feet, and to overcome this obstacle the Havasupais built a cage with logs which they filled with stones, and then from this stretched rude logs up and across, to which other logs were fastened, thus making a fairly substantial bridge from the lower to the upper stratum over which their horses as well as themselves could safely pass. The trail from this point ascends through tortuous canyons a distance of seven miles to the territory occupied by the Wallapais. Just below the entrance to Wallapai Canyon a vast mass of talus has fallen, and two hundred yards farther down, the Cataract Canyon trail goes over a portion of this talus to avoid the creek, which has here crossed from the other side of the canyon and has become a rapidly flowing stream some two feet or more in depth. Attached to this talus is a large mass of solid concrete made of pebbles, rocks, and sand that have been washed down in the creek and made cohesive by the lime from the water. Here the canyon narrows again and the stupendous walls seem very near to the willow-fringed stream and the small fields. A few hundred feet farther it opens out again, and as one rides on the trail he gets exquisite views of the gray stone walls superposed on the red sandstones to the northwest. These gray and creamy sandstones, with their numerous and delicate tints and shades, afford most delightful contrasts to the glaring and monotonous red of the walls beneath. From this point we gain our first view of the so-called Havasupai stone gods, named by them "Hue-gli-i-wa," the story of which is told elsewhere. These rocky pillars with their supporting walls seem as if they were once a part of a great wall that entirely spanned the canyon, the towers being sentinel outlooks to guard from attack both above and below. The portion of the wall to the right, as one descends the canyon, has been washed away, but the tower-crowned mass to the left still preserves a broad sweep into the very heart of the canyon as if it would bar all further progress. Following the sweep of this curve and passing the wall immediately underneath the outermost of the two towers, we view from the trail which ascends a mass of talus at this point another widened-out part of the canyon, which seems entirely covered with willows, here and there overshadowed by a few straggling cottonwoods. This is where the ceremonial dances of the Havasupais take place.
