This pretty young whitetail deer doe was walking through some fresh snow when I came along. She was quite curious about me and stopped to take a good whiff.
Notice that she is doing the Flehmen response, a curling of the upper lips many mammals do to aid in their identification of scents.
Taken at the Rocky Mountain Arsenal National Wildlife Refuge.
