- Comments
- HhCk-1, Iluvektalik Island 1: This is an Early Dorset semi-subterranean sod house, partly destroyed by wind erosion but with a portion of the deposit intact. It is the only Dorset house in the area with a significant number of identifiable animal bones. Of two radiocarbon samples, SI-2510 is "almost certainly too early for a Dorset collection of this type," while SI-2509 is "clearly incorrect" (Cox, 1977: 162-163). Cox quotes a report from Robert Stuckenrath concerning S-2509: "...bones were very wet and sodden, powdery dark brown when dried, with many roots. While remaining collagen was extracted in cold 1N HCl under vacuum, laboratory experience suggests that bones subjected to heavy water percolation by ground water and/or water table variations have lost most if not all of the original organic fraction and are completely unreliable."
