I didn't think it was a problem telling about the fallen tree beng that it's
no longer an acurate description. You may have to rehide it and notify the
caretaker. Besides, the real challenge is finding the sight via Margaret,
Mary and Barbara. Chances are none of the 3 met each other. Although 2
could have. One is only meetable on a wing and a prayer. I don't think any
of these clues will help you, but they will make sense when you solve the
riddle.
