Arrive at the Waterfall

You reach the waterfall and stare up at it, trying to find a spot where a piece of paper could be hidden and not get soaked. 

Do you:

Climb to the top of the waterfall to look in some of the crevices near the top

Begin to turn over rocks to look under them

Try to call Christine because you're a bad climber and rocks are heavy so you don't want to lift them and you'd rather just see if Christine will tell you where your collection is
