Nova Scotia’s upland regions reach a maximum elevation of more than 1,700 feet (520 metres) above sea level in the Cape Breton Highlands. The most important lowlands lie along the Bay of Fundy and the Minas Basin in the southwest and along the Northumberland Strait. Many of the tens of thousands of acres of marshland created by the tremendously high tides—among the highest in the world—of the Bay of Fundy have been turned to agricultural use by dikes, which were begun in the mid-17th century by the early French settlers, the Acadians.

More than 3,000 lakes and hundreds of short rivers and streams either have been impounded by or have cut through the irregularly high and low landscapes. The best-known of the lakes, Bras d’Or on Cape Breton Island, is saline, connected to the Atlantic Ocean through three short channels. Many intruding heads of land make the lake’s 424 square miles (1,098 square km) a geographic complexity.

Nearly nine-tenths of Nova Scotia’s landmass is unsuitable for agriculture. Most of the southern peninsula rests upon acidic granite, and a large part of Cape Breton Island is mountainous, forested terrain of acidic and metamorphic rock. Podzolic soil dominates, with some gray wooded soil mainly along the Northumberland Strait. In a few pockets where clastic sedimentary rock, mostly sandstone, underlies the soil—as in the Annapolis Valley, along parts of the Northumberland Strait, and at Cobequid Bay—the land supports orchards and field crops. In 2008 the Joggins Fossil Cliffs, which hold numerous fossils from the Carboniferous Period, were designated a UNESCO World Heritage site.
