Barrett Hedges - Nature's Best Photography It is hard to understand just how vast Alaska is until you have been. Denali is over 6 million acres, and the majority of that land is all backcountry access only. Wildlife can truly live their lives and never be influenced by human activity. A large moose takes advantage of a nice evening to eat from a pond and to get away from the bugs.

Barrett Hedges - Nature's Best Photography Caribou love the high country to try and get away from the bugs. They love the fall even more because the bugs begin to die and they can focus more on eating than running away from bugs. This nice bull caribou was moving the ridge when he stopped and looked at us before going back to eating.

Barrett Hedges - Nature's Best Photography - It is not a common sight to see a cub on its mother's back. This cub had climbed up while eating grass and still had some in its mouth. Mother bear didn't seem to mind as its cub moved on her back and never tried to make it get off her. I loved that both mom and cub are eating grass in the photo.
