This paper presents the gist of informal remarks made at the Conference on Peruvian Prehistory, with some added comment pertaining to Bennett's views on the revision of the south Titicaca basin sequence. Full documentation, and the illustrative material indispensable for such comparative studies will be presented in the final report on excavations at Pucara.

Since Pucara is the only site in the northern Titicaca basin at which excavation on even a moderate scale has been attempted, its relationship to Tiahuanaco and other sites in Bolivia and southern Puno are of obvious interest, especially since the bulk of the Pucara materials represents a culture obviously sharing many of the ideas expressed in Tiahuanaco art. This being the case, the question then arises as to whether the “Classic” phase of Pucara precedes the Tiahuanaco periods, is contemporaneous with one or all of them as a regional manifestation in the northern basin, or is a later development in the southern basin tradition.
