If you've ever seen the flag of California, it's no mystery that the state mammal is the Grizzly Bear. A grizzly is recognizable from the hump on its back, which is made of what?

The Grizzy's hump is an important part of the bear's life. A large muscle, it's critical to powering their forelimbs through their daily routines. They spend a lot of time digging through earth to tear apart logs, plant bulbs, and turning over rocks. Let's not forget that they have to dig out of hibernation using that muscle.
