Still weeks before most, if not all the bears will be up from their deep sleep. It's all about food, if they had food year around they would be no reason to sleep the winter away. Since in the mountains there is little to no food from late fall to spring, then sleeping is a great adaptation for surviving the winter. The big males are the first one to get up, the female with cubs and young bears are the last, the rest spread out in the middle. This big male who looks to be near or just under 600 pounds, looked like could still use more sleep when I saw him recently.
