This is a pair of desert bighorn sheep. The image was taken on the South Rim of the Grand Canyon near the El Tovar Hotel. These rams are sizing one another up near the end of the rut season.
This grey wolf is a member of a pack known as "The Canyon Pack". The image was taken shortly after the pack had taken down a cow elk near us. After chasing their prey, they will often lay down or jump into a stream to cool down.
This bear ran past and circled a group of photographers as he made his way to a roadside carcass of a mule dear. Panning with a running animal can be difficult to get a sharp image.
