In the summer of 1929 Mr. and Mrs. Harold S. Gladwin and associates of Gila Pueblo, Globe, Ariz., assisted by Deric Nusbaum, conducted an archeological survey of small-house ruins on Chapin Mesa and in the canyon heads along the North Rim. The survey covered 250 sites. One hundred sherds were collected from each site and studied to identify the pottery types, the sequence of their development, and their relationship to pottery types of other southwestern archeological areas. The forest fire of 1934 revealed many hitherto unknown ruins. Two splendid watchtowers were found on the west cliff of Rock Canyon. In a small area at the head of Long Canyon 10 new Early Pueblo ruins were located and no doubt scores of others will be found upon more careful search. In the heads of the small canyons many dams and terraces were noted. In the stabilization program that was carried on in 1934-35 a number of artifacts were found. A certain amount of debris had to be moved in order that the weakened walls and slipping foundations might be strengthened and varied finds resulted. Axes, bone awls, sandals, pottery, planting sticks, and similar articles were most common, but a few burials were also found. In August 1934 the undisturbed skeleton of an old woman was found on the bare floor of a small ruin just across the canyon from the public campgrounds. This skeleton, of particular importance because of fusion of the spinal column, had apparently remained exposed and undisturbed through more than seven centuries. Because of the fact that no detailed, comprehensive survey has ever been made of the archeological resources of the park, the findings of new ruins, artifacts, and human remains are more or less regularly reported at the park museum. PREHISTORIC INHABITANTS OF THE MESA VERDE The so-called "Mesa Verde cliff dwellers" were not the first of the prehistoric southwestern cultures, nor were they the first human occupants of the natural caves that abound in the area of the park. Centuries before the cliff-dweller culture with its complex social organizations, agriculture, and highly developed arts of masonry, textiles, and ceramics, it is thought that small groups of primitive Mongoloid hunters crossed from the north-eastern peninsula of Asia to the western coast of Alaska. The Bering Strait, with but 60 miles of water travel, offered the safest and easiest route. Just when these migrations to the east had their origin and how long they continued cannot definitely be said, but it is thought the earliest Mongoloid hunters were in northwestern America about twelve to fifteen thousand years ago. When Columbus "discovered" America the continent was inhabited from Alaska to the Strait of Magellan and from the Pacific to the Atlantic coasts.
