Not as big as it looks either, you can see the toes from the front paw track in the front of the rear track, making it look longer than it is.
Good eye. But I think the extra extension on the toes or second set of toes is a mark left from the claws out ahead of the toes rather than where he stepped on his own track. It looks to me that the track shows claws about half way between what I'd expect on a black bear or a grizzly.
Below is a photo of a grizzly track from the Canadian Rockies, interior bear away from the coast. It is a front foot, walking left to right. On the left is the pad, then the toes in the middle, and then well in front of the toes are the blunt tipped claw marks, rght of center in the pic.
Grizz claws are curved much less than black bear claws and extend out in front farther rather than curve down closely in front of the toes. Grizz claws are curved about like a man's fingers when relaxed, and black bear claws curve about 90 degrees. Grizz claws are often worn back from digging to be fairly short and stubby, while black bear claws usually show as sharp points when the bear is walking in mud.
I have some other grizzly track photos front and back, but no hind foot tracks with clear claws showing. Don't have a black bear track photo handy to compare.
