- Comments
- BkGg-10, Morrison's Island 2: Three components include an upper occupation with Iroquoian pottery and trade goods; a middle occupation of the Middle Woodland period; and a trace of Archaic occupation at slightly deeper levels. The burial dated by S-896 was sprinkled with red ochre, and grave goods included 212 native copper beads, two large stemmed and barbed flint projectile points, a large "Hopewell preform" blade with convex sides and an angular pointed base, and a large convex-sided flint blade with a rounded base. The charcoal dated by S-897 came from what was apparently a Middle Woodland hearth, but the date is anomalously young. The hearth contained fired rocks, calcined bone, hematite and pottery. The pottery included dentate stamp, rocker stamp and pseudo-scallop shell decorations. A small partly reconstructed pot from the hearth has rocker stamping, dentate stamping, and a conical base. The charcoal of GSC-2065 is clearly not contemporaneous with the Woodland occupation. Low elevation, river-sand deposits in the Ottawa valley have been camped on by various peoples from very late Archaic to recent times, and the chances for contamination have been considerable.
