 This low, heavily eroded part of the Appalachian Mountains, along with the Pictou-Antigonish Highlands, comprises a highland across the northern portion of the peninsula with average elevations between 250–300 metres.It was heavily covered in sediment during glaciation; consequently it hosts an abundant forest as well as agricultural activities.The Carboniferous Lowlands includes carboniferous sedimentary rocks south of the Minas Basin and along the north shore of the peninsula immediately south of the Northumberland Strait.
