These aren't very good pictures, but I had to include this last wildlife encounter.
We saw this mother caribou and her calf, and stopped the bus for a few minutes to watch them. The youngster was running around playing while mom ate grass, and they gradually worked their way down the hill closer to our bus.
Then someone yelled "Bear!" and we saw the unmistakable silhouette of a grizzly on the ridge above the caribou. Even though our guides assured us that even a baby caribou can outrun a grizzly, we were all relieved when the bear turned down the other side of the mountain and disappeared from view.
