This was a nice little guy we met at Lake of the Crags. I think he was an adolescent since he was much smaller that marmots we saw on the Lower Saddle. This guy was not scared of us at all, he would walk right up to us and try to steal any crumbs we dropped while eating. He hung ot with us for much of the day sunbathing and munching (we did not give him anything to eat, you are not supposed to feed wild animals).
