Great Slave Lake, Canada – October 5th, 2009
The Great Slave Lake is the second-largest lake in the Northwest Territories of Canada, the deepest lake in North America at 614 m (2,010 ft), and the ninth-largest lake in the world.
A remnant of a vast post-glacial lake, it is 480 km (300 mi) long and 19 to 109 km (12 to 68 mi) wide, covering an area of 27,200 km2 (10,502 sq mi) in the southern part of the territory. Its volume is 2,090 km3 (500 cu mi).
The Hay and Slave Rivers are its chief tributaries. It is drained by the Mackenzie River. Though the western shore is forested, the east shore and northern arm are tundra-like. The southern and eastern shores reach the edge of the Canadian Shield.
The East Arm of Great Slave Lake is filled with islands. The Pethei Peninsula separates the East Arm into McLeod Bay in the north and Christie Bay in the south.
