This paper limits itself to a deruption of four complexes revealed by our excavations at Saglek Bay, northern Labrador, during the years 1969, 1970, and 1971. A "Pre-Dorset com plex and three phases of a considerably longer Dorset Eskimo occupation are examined and some comparison within the Saglek sequence and a few comparisons with nearby geographic areas are offered. No attempt is made to generalize about Paleoeskimo cultures in the entire Canadian Arctic, especially as regards causative relationships, since such attempts seem premature given our present lack of control over basic cultural and environmental data.
