About 70 percent associated with area drained is over 3, 000 feet (900 m) large, and human exploitation with this rather remote location was fairly recent. The all-natural beauties for the lake training course (particularly its spectacular canyon section) plus the surrounding country have actually nonetheless remained reasonably unspoiled.

Below this canyon the Fraser turns westward to move placidly across an to its debouchment near , B.C. The , which gets in the Fraser about 145 miles (235 km) from the lips, is the most important of numerous tributaries, some of which boost in extensive mountain lakes.

The economic climate associated with Fraser River basin is dependent primarily on . Coniferous forests cover all the Interior Plateau, except in the dry, south valleys, that are covered with slim strips of grassland regarding the lower slopes.
