New Brunswick GeographyThe Appalachian Mountain ranges, a chain of ancient, eroded mountains, stretch across much of New Brunswick. They contain Mt. Carleton, standing at 817 m (2,680 ft), the highest point in the province.
The undulating landscape of the New Brunswick Lowlands front the Northumberland Strait, extending southeast to land's end.
From the rolling hills of the Miramichi River Valley in central New Brunswick, the land slopes south to the Bay of Fundy where the Caledonia Highlands and St. Croix Highlands extend along the coast. Maximum elevations above sea level here reach 300 m (985 ft.)
The Bay of Fundy itself is known for its high tidal range and the bay is claimed to have the highest vertical tidal range in the world. In fact, over 110 billion tons of water flow in and out of the bay during a twelve hour tidal period. Want proof? Here it is!
Western and southern New Brunswick are drained by the Saint John River and its many tributaries. The river begins in northern Maine and flows all the way to Saint John and the Bay of Fundy.
Additional rivers of note within the province include the Canaan, Kennebecasis, Miramichi, Napisiguit, Petitcodiac, St. Croix and Restigouche
Grand Lake is the province's largest freshwater lake. The Chipnuneticook Lakes include several smaller lakes along the International Boundary between the U.S. State of Maine and New Brunswick.
