Fast Facts - North Slave

The Deepest Waters

Not far offshore from the little town of Lutselk’e, the bottom drops out of Great Slave Lake. Toss a rock from your boat and it’ll plunge through the dark cold water for 2,014 feet – finally stopping at the deepest point below sea level in North America.

The Oldest Rock

Cropping up from a mid-river island north of Wekweeti is a mound of stone from the Earth’s beginnings. At more than 4 billion years old, the Acasta Gneiss is the most ancient exposed rock ever found.    

The Richest Ground

The North Slave was once home to an array of gold mines, but now it produces something even richer. Canada’s first diamonds were discovered here in the 1990s. Now, thanks to North Slave mines, we’re the world’s third-largest diamond producer.

The Coldest Road

For two months each winter, the North Slave is traversed by the planet’s longest ice road – a 600-kilometre frozen highway rolling across lakes and tundra nearly to the Nunavut border. Though designed for mining transport trucks, this private road carries hunters, photographers and adventurers as well.

The Newest Park

Already home to five national parks, the Northwest Territories will soon welcome a sixth – Thaidene Nene, encompassing the East Arm of Great Slave Lake, home to big fish, tall cliffs, muskoxen, waterfalls and more.
