When Morris first undertook the excavations at Aztec it was his intention, and that of the American Museum of Natural History, to excavate the ruins completely. However, the undertaking was a massive one. World War I intervened, with all its uncertainties, and funds frequently ran short. In the later days of the excavations, Morris realized there was an advantage to leaving parts of any ruin unexcavated so that better archeological techniques in the future might extract information of which he was unaware. At present, the National Park Service feels much the same way. Perhaps 25 or 50 years from now further excavations may be undertaken in this area, but for the present, the ruins will be left as they are, complete with their feeling of mystery. _The Aztec Ruins Today_ Aztec Ruins National Monument consists of an enclosed area of 27 acres containing six major archeological complexes of rooms and structures, and at least seven or eight smaller mounds which may contain structures or may simply be trash and refuse mounds from the larger occupation zones. Two of these major complexes have been excavated: the West Ruin and the Hubbard Mound. Two of the others—the East Ruin and Mound F—have been tested. Mound F is evidently very similar to the Hubbard Mound. [Illustration: Aztec Ruins during excavations of the 1920’s.] The East Ruin, if excavated, might be similar in most respects to the West Ruin, both in appearance and time of occupation. As to whether the smaller mounds contain trash or house remains, only thorough archeological investigations can tell. Morris’ diggings and subsequent small tests have indicated there may be earlier (Developmental Pueblo) remains underlying the main prehistoric complexes. Also, such remains might still be found under the windblown sand in the flatter areas between the major ruins. No real archeological work has ever been done in the monument area to determine the possible extent of such earlier remains. The two main sites seen by the visitor to the monument are, therefore, the West Ruin and the Hubbard Mound. The West Ruin was the one first entered by early settlers in the late 19th century. The profuse remains caused extensive digging and looting for about a decade. Then, under the ownership first of John R. Kuntz and later of H. D. Abrams, the area was given a certain amount of protection. During 1916-21, the American Museum of Natural History excavated extensively in the West Ruin under the guidance of Morris. Today, three-fourths of this ruin has been excavated, cleared, and stabilized so that you may gain a firsthand impression of its original appearance. The remaining one-fourth is largely unexcavated and, for all anyone knows, may contain archeological riches equal to any recovered in the early days or during the excavations by the American Museum of Natural History.
