Black Marmots

This dark marmot lives in Grand Teton National Park, and the more typical colored one below lives 100 miles north in Yellowstone National Park. A melanistic population of yellow-bellied marmots have persisted in the Tetons for more than 80 years, with 15-23% of the population consisting of these "black marmots."
