Since 1982 I have been finding and filming the grizzlies in and around the Big Sky area and the northwest corner of Yellowstone Park. Grizzly I filmed in 1996 ended up being a very close encounter. This is a sow grizzly filmed on the way to Fawn Pass, DO NOT try to get this close unless you know what your doing. Claw are out about 3 inches from the toes. Not well seen in this picture.look closely above the toes at the top of the picture.
Grizzly scat is very black and full of grass and small animal bones and teeth.
The wetter the scat the closer the grizzly. This is a grizzly clawing tree, you know you're in thier country when you see this. These claw marks are in the tree about 3 inches deep. Grizzly diggings are very deep and much larger than your coyote diggings, look for grizzly tracks around the holes. If no other signs mean anything to you,this one should.
