About the lake
Great Slave Lake has a branching shape with a long eastern arm that reaches 614 m. This is the deepest point in any North American lake and lies below the bottom of every Great Lake.
Its western part, by contrast, is shallow and murky. That asymmetry means its 28,568 km² surface holds about 1,580 km³ of water. For five winter months its ice is thick enough to carry trucks.
