In the preceding part of this study I have tried to determine the functional trait constellation and cultural orientation of the Mog oil on people. In the following pages I shall attempt to trace the relationships of this group to other Southwestern groups, both prior and contemporaneous. In this paper I am not concerned with the relative taxonomic status of the various groups. Haury, Colton, Reed, Martin, Rinaldo, Nesbitt, Brew, and others have discussed various aspects of this problem at some length. Much of the Mogollon controversy has been philosophical and semantic in orientation and it does not seem necessary to review the various arguments here. Clearly there were temporal and cultural differences, as well as similarities, between these groups, and it is the examination of the nature and extent of these aspects that I propose.
