Most of my winter photography of caribou has been in the treeless arctic. The snow covered spruce trees make this image a little unique to my experience. This year on the north side of the Brooks range the caribou herds moved west and virtually none were visible along the Dalton Highway road corridor. This scene was captured near Finger mountain, from a group of perhaps 50-75 animals, a mix of cows and bulls.
