Motorcyclist Tim Bartlett caught this image of a wolf chasing him on a highway in Kootenay National Park in British Columbia, Canada, June 8, 2013. Bartlett said the animal kept after him for more than half a mile, sometimes getting within several feet. Bartlett stopped on the road to take pictures of his pursuer; when he accelerated again, the wolf disappeared into the forest. (AP Photo/Tim Bartlett) ( Wolf Chase )
