Labrador Peninsula

Location and geography

The peninsula is surrounded by sea on all sides, except for the southwest where it widens into the general continental mainland. The northwestern part of the Labrador Peninsula is shaped as a lesser peninsula, the Ungava Peninsula, surrounded by Hudson Bay, the Hudson Strait, and Ungava Bay. The northernmost point of the Ungava Peninsula, Cape Wolstenholme, also serves as the northernmost point of the Labrador Peninsula and of the province of Quebec. The peninsula is a plateau threaded by river valleys. There are several mountain ranges. The Torngat Mountains, located in the northern part of the peninsula, contain the highest point of the peninsula, Mount Caubvick, which at 1,652 metres (5,420 ft) is also the highest point of mainland Canada east of Alberta. The mountains also host Torngat Mountains National Park, the only national park of Canada in Labrador. The park is located in the province of Newfoundland and Labrador, and the adjacent Kuururjuaq National Park is located in the province of Quebec.

Hydrology

Due to it being covered almost entirely by the Canadian Shield—a vast, rocky plateau with a history of glaciation—the peninsula has a large number of lakes. The province of Quebec alone has more than half a million lakes of varying size. The largest body of water on the Labrador Peninsula is the Smallwood Reservoir, but the largest natural lake is Lake Mistassini. Other lakes of note include the Manicouagan Reservoir, the Caniapiscau Reservoir, and the La Grande 2 and La Grande 3 reservoirs. Due to a history of hydroelectric development, the majority of the larger freshwater lakes on the peninsula are reservoirs. In addition to an abundance of lakes, the peninsula also has many rivers. The longest, the La Grande River, is 900 kilometres (560 mi) long and flows westwards across nearly half the peninsula, emptying into James Bay. Other rivers of note include the Eastmain River, Rupert River, and Churchill River.
