在巴芬岛中部，描绘了一条源自古生代基岩的冰川分散序列，从东-东北-西-西南延伸。这些不稳定地层的岩性表明，它们来自西部奥陶系船点组B段地层，该地层目前已被福克斯盆地东部第四纪沉积物淹没或覆盖。这些古生代的不稳定物质被从福克斯盆地带到巴芬高地和戴维斯高地的西部边缘。可以推断，它们至少到达了埃卡卢加德峡湾和霍姆湾的东部。
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.
