can't get through (Rise of the Tomb Raider)

Open the map. Open the list of side missions. Select this mission (make it active) a flashing round will appear on the map. And now stand in the center of the round and look up. She sits either on a tree, or on a small wooden gate. There seems to be a metal grill around. Here somewhere on top of the gate or lattice. I do not remember exactly.
