I came across a family of Yellow-bellied Marmots while visiting Grand Teton National Park. A group of us were watching for a female Grizzly and her two cubs. I never did see the Grizzly, but these Yellow-bellied Marmots kept me entertained while I watched for the Grizzly.
I counted a total of four little ones with the mom being the fifth. I was hoping to get a photo with all of them together, but that didn't happen.
