The importance which it is believed should attach to the site on which a ruin is found will be apparent from the above. It was certainly a prominent element in the De Chelly group. A study of the detailed map here published will illustrate how completely the necessity for proximity to an area of cultivable land has dominated the location of the settlements, large and small; and a visit to the place itself would show how little influence the defensive motive has exercised. Near the mouth of the canyon, where cultivable areas of land are not many, there are few ruins, but those which do occur overlook such lands. In the middle portion, where good lands are most abundant, ruins also are most abundant; while above this, as the rocky talus develops more and more, the ruins become fewer and fewer; and in the upper parts of the canyon, beyond the area shown on the map, they are located at wide distances apart, corresponding to little areas of good land so located. Not all of the available land was utilized, and only a small percentage of the available sites were built upon. Between the mouth of De Chelly and the junction of Monument canyon, 13 miles above, there are seventy-one ruins. A fair idea of their distribution may be obtained from a study of the detailed map (plate XLIII), in conjunction with the following figures: I. Old villages on open sites occur at the points marked 12, 41, 52, 17_a_, 55, 60, 61, and 67; in all, nine sites; principally in the upper part of the canyon. II. Home villages on bottom lands, located without reference to defense, occupy sites 3, 4, 17, 20, 28, 48, and 51; in all, seven sites. Probably there are many more ruins of this class and the preceding, now so far obliterated as to be overlooked or indistinguishable. III. Home villages on defensive sites occur at the points marked 5, 10, 13, 15, 16, 27, 31, 32, 34, 36, 37, 40, 44, 47, 59, 62, and 66; in all, seventeen. This includes many sites where the settlements were very small, often only a few rooms, but there is always at least one kiva. IV. Cliff outlooks and farming shelters occupy sites 2, 6, 7, 8, 9, 11, 14, 18, 19, 21, 22, 23, 24, 25, 26, 29, 30, 33, 35, 38, 39, 42, 43, 45, 46, 49, 50, 53, 54, 56, 57, 64, 63, 65, 68, 69, and 70; in all, thirty-seven, or more than half. Some of these sites are now marked only by Navaho remains, and possibly a small percentage of them are of Navaho making, but the sites which are clearly and unmistakably Navaho are not mentioned here. Of all the sites only one (No. 7) is actually inaccessible without artificial aid.
