Comments
GbTo-18, Dodge Island: This small island is half covered by a shell midden up to 3 m thick, underlain by thick humus containing chipped stone implements. MacDonald believes that GaK-1876 may have been contaminated by ground water saturation. However, the recent date may reflect a shift in settlement pattern to areas farther from the beach due to the growth of the village. The same applies to GaK-1877, from a level slightly below GaK-1876. GSC-1439 tends to confirm GaK-1877. GaK-1879 was from the base of the cultural deposit, on top of sterile gravel, and is confirmed by other basal dates from the coast which suggest a maximum age of about 5000 years for shell midden. The same comment applies to GaK-1880.
