A Yellow-bellied marmot (Marmota flaviventris) hanging out in the rubble at Sheepeater Cliff in Yellowstone National Park, Wyoming. They are also commonly found around the park cabins where they play under the steps and communicate with each other using loud whistles. Another name they go by is Rock Chuck.
