A glacial dispersal train of erratics derived from Paleozoic bedrock has been delineated stretching east-northeast–west-southwest across central Baffin Island. The lithologies of these erratics suggest a derivation from strata of member B of the Ordovician Ship Point Formation to the west, which are presently either submerged or covered by Quaternary sediment in the eastern part of Foxe Basin. These Paleozoic erratics were carried from Foxe Basin onto the Baffin Upland and the western edge of the Davis Highlands. They can be inferred to have reached at least Ekalugad Fiord and the eastern part of Home Bay.
