17. One thing I wanted to do while up here was take a good shot of the Trough and see if I could find hikers in the picture. I expected that in some cases it may be difficult to tell the difference between hikers and rocks, so I took two photographs like this one a few minutes apart so I could compare the two very closely and find differences. Sure enough, there they are! I found about eight hikers in this photo and magnified a spot with two.
