Not long after crossing into British Columbia from the Yukon Territory we encountered a sign warning of wildlife on the highway. Sometime later we found them, an obstinacy of Wood Bison were grazing along the highway's edge so, naturally I stopped to make a few images. Wood Bison are found only in Canada and are a subspecies (Bison bison athabascae ) of the American Bison. Wood Bison are slightly heavier and have a darker coat than the cousins the Plains Bison. We would later encounter a second group but in a location in which I had no place to park and make images.

A couple of hours later we came upon another subspecies as the highway took us through BC's Muncho Lake Provincial Park. Ovis dalli stonei , commonly known as Stone Sheep, are a subspecies of Dall Sheep that are found in British Columbia and in parts of the Yukon Territory. The Dall Sheep of Alaska and the western Yukon are completely white while the Stone Sheep are gray to grayish-brown with white patches. (Just to confuse the issue more, a third subspecies called Fannin's Sheep can be found in parts of the Yukon which are intermediate between the other two.)

If they had been kind enough to hang around the day would have had a "subspecies trifecta": As we were about to leave Stone Mountain Provincial Park a cow and calf Mountain Caribou crossed the highway (safely) in front of us but, unfortunately, disappeared quickly into the forest before I could get stopped (let alone get pics). All in all a good day for wildlife along the road to Jasper later in the week.
