These high-altitude residents are tons of fun to watch and occasionally will stop their scrambling long enough to pose for a picture. Such was the case with this cutie near the top of Trail Ridge Road in Rocky Mountain National Park a couple of weeks ago. It sat nice and close allowing me to get a great close up of it with a glint in its eye from the morning sun and a nice view of its coarse, warming fur.
Yellow-bellied Marmots can be found above 6,500 feet in grassland, meadows and talus fields. Here in Colorado, in my experience, they are most likely to be found near or above timberline (11,000 feet or so) and in talus fields.
