Yeah, that's the first thing I noticed too. But unless he's a hybrid, the ears, lack of forehead crease, and white patches give it away. Compare to this one from later on in the trip (also eating clover.) Interesting bear either way and glad he stuck around for pics.
I'm with black bear for this. The look of a hump is how he was standing with a shoulder high. His/her head looks pretty big, so it's probably a fairly young bear - the head grows up first, then the body catches up. A big bear will look like it has a small head. In my case, it's just too much weight everywhere BUT the head...
Excellent ride report, CC.
