CINDER CONES, PLATEAUX AND CANYONS

... There's the land (Have you seen it?)
It's the land that I know,
From the big, dizzy mountains that screen it,
To the deep, deathlike valleys below ....

from "The Spell of the Yukon",  
Robert W. Service

THE LAND:

This is a large, complex region of mountains, broad plateaux, plains, basins and trenches. Glaciers and volcanoes have shaped this area extensively. The work of glaciers is present throughout, although only small icefields and glaciers exist today. A good example of active glaciers is found in the Kluane-Aiskinik area adjoining Kluane National Park Reserve. This is a rugged area where alpine glaciers have carved uplands into angular mountains and U-shaped valleys. The Yukon River-Southern Ogilvies area includes mountains over 2,500 metres high with both glaciated and unglaciated mountain landscapes. Much of this area was spared from the Pleistocene glaciers, resulting in landforms that are rarely found elsewhere in Canada.

Several major rivers have carved deep canyons. The "Grand Canyon of the Stikine", where the river flows for 64 kilometres between sheer lava walls 100 metres or more in height, is one of the most spectacular river canyons in Canada. The largest lakes in British Columbia are found in this region.

Mount Edziza, the apex of the Spectrum Ranges, features well-preserved examples of recent volcanic activity, including cinder cones, calderas, lava plains, dykes and other evidence of the earth's restlessness. Mt. Edziza Provincial Park includes many of these volcanic features.
