The archaeology of the Puebloan or Anasazi people of the Southwest has been the subject of many investigations, to the neglect of partly contemporaneous peoples of different cultural background. However, the existence of a non-agricultural people as predecessors and contemporaries of the Puebloans has been postulated on general, theoretical grounds. It comes, therefore, with something of an expected surprise to realize that in the heart of the Puebloan area of central New Mexico at least one non-ceramic cultural complex existed. The present investigation gives only faint clues to the antiquity of this complex and to possible relations of the people represented by these artifacts with the Puebloans. A later and derivative Lobo complex is associated with Pueblo I and Pueblo II pottery and represents a close association or perhaps a fusion of a hunting people with the Puebloans. The present paper deals with the location of the sites, the artifacts found in them, and the general archaeology. The following paper, by Bryan and McCann, describes the local geology and makes a geological and archaeological correlation with other areas in the Southwest. The two papers should be regarded as a mere introduction to a field of archaeological research that has heretofore been much neglected.
