Yellowstone Mammal Catalog
Mammals of Yellowstone and Grand Teton National Parks
While over 60 mammal species are present in the parks, many of these creatures are elusive, small, or nocturnal. Often, they are some combination of the three. For that reason, my photo safari contains only some 34 mammal species. I hope to continue to add to this collection with time.
