A most striking feature of doorways is the occasional departure from the quadrangular form, seen in some ruined villages and also in some of the modern houses of Tusayan. Fig. 82 illustrates a specimen of this type found in a small cliff ruin, in Canyon de Chelly. Ancient examples of this form of opening are distinguished by a symmetrical disposition of the step in the jamb, while the modern doors are seldom so arranged. A modern example from Mashongnavi is shown in Fig. 83. This opening also illustrates the double or divided transom. The beam ends shown in the figure project beyond the face of the wall and support an overhanging coping or cornice. A door-like window, approximating the symmetrical form described, is seen immediately over the passage-way shown in [Pl. XXII]. This form is evidently the result of the partial closing of a larger rectangular opening.

Fig. 84 shows the usual type of terraced doorway in Tusayan, in which one jamb is stepped at a considerably greater height than the other. In Tusayan large openings occur in which only one jamb is stepped, producing an effect somewhat of that of the large balcony openings with flights of stone steps at one side, previously illustrated. An opening of this form is shown in Fig. 85. Both of the stepped doorways, illustrated above, are provided with transom openings extending from one roof beam to another. In the absence of a movable door the openings were made of the smallest size consistent with convenient use. The stepped form was very likely suggested by the temporary partial blocking up of an opening with loose, flat stones in such a manner as to least impair its use. This is still quite commonly done, large openings being often seen in which the lower portion on one or both sides is narrowed by means of adobe bricks or stones loosely piled up. In this connection it may be noted that the secondary lintel pole, previously described as occurring in both ancient and modern doorways, serves the additional purpose of a hand-hold when supplies are brought into the house on the backs of the occupants. The stepping of the doorway, while diminishing its exposed area, does not interfere with its use in bringing in large bundles, etc. Series of steps, picked into the faces of the cliffs, and affording access to cliff dwellings, frequently have a supplementary series of narrow and deep cavities that furnish a secure hold for the hands. The requirements of the precipitous environment of these people have led to the carrying of loads of produce, fuel, etc., on the back by means of a suspending band passed across the forehead; this left the hands free to aid in the difficult task of climbing. These conditions seem to have brought about the use, in some cases, of handholds in the marginal frames of interior trapdoors as an aid in climbing the ladder.
