 The peninsula can be divided into two distinct geological regions north and south of a fault line (the Cobequid and Chedabucto faults) extending between the Bay of Fundy sub-basins of the Minas Basin and Cobequid Bay in the west, through to Chedabucto Bay in the east.The northern portion of the peninsula is dominated by the Avalon Uplands (the Cobequid Hills and Pictou-Antigonish Highlands) and the Carboniferous Lowlands, the latter of which straddles the fault zone.The Cobequid Mountains contain the highest elevation points on the peninsula.
