Busy butterballs

David Lukas

Golden-mantled ground squirrels are busy occupants of campgrounds and picnic areas in mountain areas throughout the West. Prepping for winter hibernation, they're putting on some serious layers of body fat and carrying so many seeds that their cheeks bulge out to twice the width of their heads. Full of wonderful antics, they're a reason all to themselves for going camping this summer. Here are some great places to see them.
