Rivers of elk flow through it. Yellowstone in summer functions like the mixing-zone center of a wheel for elk migrations that enter the park and then spoke out in many different directions come fall and winter.  The amazing phenomenon persists because the ancient pathways have not been fragmented by human development. Key to their health also is having healthy habitat to sustain mother wapiti and their calves. In turn, elk are an important staple for wolves and grizzlies and scavengers.
