Nature's fluffy mountaineers

Elusive mountain goats, like these three in Canada's Yukon Territory, rarely let themselves be discovered as plainly as this. Despite its name, the hooved wild mountain goat is not a true goat—in fact, it's the only genus and species of its kind in the world. Found only in northwestern North America, its closest relatives aren't domestic goats, but the chamois of Europe and the goral and serow of Asia.
