The largest and stockiest of local squirrels is the yellow-bellied marmot. The frumpy (cute) animals that can vary in length between 19 and 26 inches and can be identified by the dark head with a yellowish band across the bridge of the nose. Marmots can be found on the rocky subalpine slopes which are close to sources of grassy or herbaceous vegetation where they excavate networks of burrows to protect them from the freezing temperatures. They live in harem colonies and like to bask in the sun of the warm summer days. Sometimes they are known as woodchucks or groundhogs.
