This image was taken in Yellowstone National Park in the spring of 2018.
These two beautiful grizzly bears are playing, not fighting. The bear on the right is the mother of the three and one-half year old on the left. Notice the mother's claws carefully being kept away from her offspring.
Eventually mother grizzlies abandon their young or aggressively force them to leave, to start a new family. Shortly after this image was taken, a large male grizzly came upon the scene and chased the young bear out of its mother's life.
