399 is the bear study number for this well-known bear in the Grand Tetons. She is 25 years old in this image, which is getting old for a grizzly bear. She has had twins and triplets before but never emerged from the den with 4 cubs. Miraculously she emerged in the spring of 2021 with all four cubs surviving their first year.  I have not ever seen this in my lifetime.
