"The Eastern Entrance of the Park is reached by a celebrated road from Cody, Wyoming. Not far from Cody on this route is the Shoshone Canyon and the Government dam, three hundred twenty-eight feet in height. This canyon is so precipitious that a six different points it was necessary to tunnel the cliffs in order to make an automobile road through this spectacular canyon possible. Near this point is the famous hunting lodge of the late Col. W. F. Cody for whom the town of Cody and this road were named."
