okay, how about this:

instead of marking the trees, Jason takes pictures with his phone of trees and rocks that stand out to serve as landmarks and uses them to find his way back to the library. Then when he goes to the library the final time, he leaves his phone at home on purpose because he doesn't want to be disturbed, and just shutting the phone off somehow isn't enough. Melissa finds the phone, as they are looking for clues to Jason's disappearance, and she looks through the pictures, and tries to find out where they were taken. It probably takes her a while, but who knows how long Jason is in the library towards the end. It might not be believeable that she went alone, though.
