Fig. 112. The archway at the northern entrance to Yellowstone Park, 

 dedicated by President Roosevelt in 1903. The boundary fence across 

 the Gardiner River flats at this point helps to hold the antelope (but 

 not the elk and deer) from migrating down the valley to their natural 

 winter range, where they would be slaughtered by Montana hunters.
