Photo Of The Day 15

Canada, 1985

Photograph by George F. Mobley

Frost-flecked tundra pools dot the landscape of Canada's North Yukon National Park. Treeless regions found in and around the Arctic, tundras are among Earth's coldest, harshest biomes. Permafrost, cold, wind, and scant rainfall make it difficult for most plants and animals to survive here.
