Grizzly bears don't actually hibernate.
What they do is called torpor. Their heart rate and breathing slow down dramatically, and they can go months in the den without eating or drinking, but their body temperature only drops a few degrees. True hibernators go much colder and much deeper than that. A grizzly can still wake up and move if it needs to.
The bears we visit in the Khutzeymateen spend the summer building up fat reserves on salmon, then settle into torpor for the winter, living off those reserves until spring. They'll be back out foraging along the shoreline when spring comes.
