The Barren ground caribou inhabits much of Alaska in large nomadic herds. While both sexes have antlers, the male or bull caribou is the majestic one, whose rack is sought after by sportsman. They are well suited for travel in heavy snow, and cover hundreds of miles during their migration routes across Alaska's tundra. The photographs here were taken in interior and arctic Alaska, in various seasons. Read more caribou natural history information. All images are available to license as stock photography and may be purchased as art decor prints for home or office.
