Enter Yellowstone Park through the North Entrance in Gardiner, Montana. Travel through Mammoth to the Tower/Roosevelt Junction. Go straight past Tower Falls until you hit Dunraven Pass.
During most of the summer of 2010, a grizzly sow and her two cubs of the year made their home along Dunraven Pass in Yellowstone Park. This tiny cub created quite a traffic jam when he decided to cross the street in pursuit of his mother and sister.
