 Geologically, the Baffin Mountains form the eastern edge of the Canadian Shield, which covers much of Canada's landscape.The ranges of the Baffin Mountains are separated by deep fjords and glaciated valleys with many spectacular glacial and ice-capped mountains.The snowfall in the Baffin Mountains is light, much less than in places like the Saint Elias Mountains in southeastern Alaska and southwestern Yukon which are plastered with snow.
