Someone's plannin' somethin'

Do you see it?
This morning while making beds and straightening up a bit this is what I saw.

Now do you see it?
It was on the top of his pile of books which means it was the last book he read last night or this morning - he's flipping through his "The High Sierra - Peaks, Passes and, and Trails" book again. There are 3 pages that are bookmarked, too.
