ok lol this is going to sound hella dorky but if you look at the jaw line its def a deer because the elk jawline is more horse shaped and has larger cheek pockets.. while the deer(in the pic) has a very slender jawline... also with size comparison if it was a baby elk it would have the spots which last well into its first year... thus my conclusion it is def a deer .... and that is werd

compare the body structure and the jawlines
