One of the odder curiosities of the National Bison Range is a huge pile of antlers near the visitors' center. For many years, rangers have been collecting antlers that they find in the field -- from any of the several species of animals that live in the range -- and stacking them into a huge mound at least ten feet high and over six feet in diameter.

This is a somewhat more abstract view of the stack, showing the interesting textures and shapes of the antlers.
