On the western margin of the ruin, and nowhere else within it, there are traces of another kind of construction which was not found elsewhere within the canyon. This method is known to the Mexicans as "jacal," and much used by them. It consists of a row of sticks or thin poles set vertically in the ground and heavily plastered with mud. At present not one of these walls remains to a height of 6 inches above the ground, but the lines of poles broken off at the ground level are still visible. The ground at this point is but 3 or 4 feet above the general level of the bottom. The ground plan shows the occurrence of these wall remains on the western edge of the site. They are all outside of but attached to what was formerly the exterior wall on that side. There are remains of four Navaho burial cists in the lower ruin, at the points shown on the ground plan. These are constructed of stones and mud roughly put together in the ordinary manner, forming thin, rounded walls; but these can not be confounded with the other methods of construction described. Three of the cists have long been in ruins and broken down; the one on the east is but a few years old. Access to the upper ruin can now be had only with much difficulty. In the western end of the cave there is a single room placed on the cliff edge, and between this and the end of a wall to the right a small stick has been embedded in the masonry at a height of about 2 feet from the rock. The cliff here is vertical and affords no footing, but by throwing a rope over the stick a man can ascend hand over hand. During the period when the houses were occupied, access was had in another and much easier way, through a doorway or passageway nearly in the center of the ruin and directly over the point where the lower village was four stories high. The roof of the lower structure was less than 4 feet below the floor of the cave; yet there is no doubt that a doorway or passageway existed also at the western end of the cave, as the western end of the wall on the right of the stick is neatly finished and apparently complete.
