TREASURE MAP 1/1
Coordinates: [712708; 3416012]
Note: In the second section of the caves, in the spot where Lara blows up a gas mist to move a large crate. Examine the structure where the crates had been placed and notice you can grab onto the edges.
Make your way up until your reach a small wooden gallery. Take the Map from it; it details the location of all missing collectibles (except for Firestarters) (reward: 25 XP).
