No elk in this area , not even a century ago but bison ,horse , even cow , I suppose it could be any of them . I should have put a ruler next to it in the photo so you could see it size (maybe next time ) it is about 5-6 inches long . It seems to me to be too large for our deer . Perhaps a butcher could tell us about what size animal it was .

She has a quite a collection . Here are couple more she found not to many miles away from the bone . The one on the right is about 4-5 inches .
