Grizzly Sibling Rivalry

I was overjoyed when I was able to witness this interaction!  We had pulled over to set up at the base of Mt. Washburn in Yellowstone National Park.  I wasn't given the chance to properly set up my equipment before a mother grizzly bear and three grizzly bear cubs came bounding out the tree line!  These two grizzly cubs felt especially feisty and gave me the opportunity to brace my camera against a tree and capture this photograph before they all ran up the adjacent ridge and into the forest!
