At the Mammoth Ranger Station we toured the exhibits so Anna could get a preview of the animals we would be looking for during our 3 day stay. The skull and antlers of a 6x6 bull elk was a good indication of the size of some of the animals. Other exhibits included bison and mountain sheep horns plus antelope, moose and elk antlers and fur from a number of animals. Antlers are very heavy – it's amazing the animals can keep their heads up.
