 Tundra is characteristic of the land north of the tree line; there the native people depend on hunting, arts and crafts, fur-trapping; and they obtain many resources from fish, seals, reindeer, and caribou.The majority of the development in this area takes place south of the tree line, where the land is covered with soft woods and rich minerals.Two of the world's largest lakes (Great Slave and Great Bear) are located here.
