An arctic ground squirrel pauses to scratch itself near The Eielson Visitors Center at mile 66. So many different predators eat arctic ground squirrels that Adolph Murie called them the "staff of life" in Denali. They are one of the most important summer food sources for golden eagles, foxes, and grizzly bears. They are quite jittery and vocal. Their dens have several entrances and exits making it difficult for predators once they are inside their den.
