Brotherly Love (Hoary Marmots)

The rough and tumble play of these Hoary Marmots reminded me of the human play fighting I posted less than a week ago. ( I do not know if they are in fact "brothers" and actually they looked full size to me so maybe they are adults.)  These hoary marmots were high up on Blackcomb Mountain near Whistler at about 8,000 feet elevation.
