Hoary Marmots are the cute, pudgy, twenty plus pound ground squirrels that have evolved to live quite happily in the hostile alpine areas around Whistler.  In the northwest of North America, marmots have a distinct grey in their hair, a hoary colour, so have been named hoary marmots. They manage to survive quite happily in the alpine, largely by hibernating for 8 months of the year and largely for having a surprisingly varied array of food in such an inhospitable environment.
