Nature's fluffy mountaineers

Mountain goats like this trio in Canada's Yukon territory, aren't ovine but bovine. That is to say they're related to antelopes and cattle, not goats and sheep. But these sure-hoofed critters have no trouble ascending icy mountain slopes, taking slow steps as their white fur blends in with the subarctic snows. They aren't confined to these northern wilds, though: The mountain goat's habitat extends as far south as the Colorado Rockies—there these mountain bovines go by another common name: Rocky Mountain goats, but they're still not goats.
