You may hear the marmot before you see it! He will have spotted you from afar and at your approach he will probably run off to hide in his burrow. But if you are patient and quiet, she will come out very quickly and you can admire her quietly.
With an unobstructed view to watch for predators, her "home" is a burrow that she has dug and where she takes refuge in case of danger after having warned everyone with her distinctive whistle. Most of the time she stays outside to feed on roots, leaves and flower stems and also to bask on a rock in the sun.
