There were chipmunks everywhere on the way up to Angel's Landing. What's amazing was that we gave one of them (pictured left) a Powerbar wrapper. It ate some of the scraps, and then went to exchange the smell to the other chipmunk, who in turn wasn't interested.
There was about a 0.5" window open for me to take this shot. Not counting the awesome view at the top of Angel's Landing, this one pretty much made the trip.
Unfortunately I didn't have time to take off my polarizer, so many of the photos turned out fairly underexposed and high in noise/grain.
