TREASURE CHEST

All treasure chests require the lock pick to open. Once you have acquired this tool, fast travel to the Plane Wreckage Base Camp. Then head south/southwest toward the edge of the ravine. At the spot indicated here on the map, climb down the cliffside then over to the left to reach a hidden cave with the treasure chest and document #13. The chest contains an Artifact (a Silver Mirror from the Day in the Life of a Paititian Story). The walkthrough includes details and screenshots. Climb back up the way you came, return to the base camp, and fast travel out to wherever you left off. (Click screenshots to enlarge.)

NOTE: You can also spot the chest through the wooden slats set into the ground near the cliff's edge, shown in this screenshot, but you can't break through the slats, so you'll have to climb down the cliff to get there.

RELIC 2 - Handkerchief (Expedition Unknown)

This is in the same area as the first relic. If you missed it, fast travel to the Plane Wreckage Base Camp. Then follow the path to the north toward a small pool, where you'll find the relic sitting on a shelf. (Click image for more and larger screenshots.)

RELIC 4 - Grave Marker (Expedition Unknown)

This relic is in the Crypt of Rimak, The Storyteller. Fast travel to the Plane Fuselage Base Camp then head northwest to the crypt entrance. The relic is just inside the tunnel. When you're done, follow the path in this screenshot. Climb the rocks to the south, swing over to the plane fuselage, and slide down to the campsite. (Click screenshot to enlarge.)

RELIC 6 - Bowl of Powder (Day in the Life of the Inca)

This relic is in the area with the drawbridge puzzle. You can reach it from the Plane Fuselage Base Camp by following the path to the southeast or from the Jungle Ruins Base Camp by heading to the northwest, as indicated by the arrows in this map detail. You'll find the relic at the top of the steps near the monolith. When you're done in this area, return to either camp and fast travel away. (Click screenshots to enlarge.)

DOCUMENT 3 - Jack's Journal 6 (Expedition Unknown)

This document is at the south end of the area with the pool, where Lara cut down her gear early in the level. To reach it, start at the Plane Wreckage Base Camp and head due south. In the bottom corner of the area, near the base of the tree you climbed to reach relic #3, is an opening in the rocks. Go through and drop down on the ledge beyond to find the document. (Click image for more and larger screenshots.)

DOCUMENT 5 - Jack's Journal 3 (Expedition Unknown 2)

This document is on the approach to the Plane Fuselage Base Camp. If you missed it the first time, fast travel to the camp and head down the path to the northwest. Dive into the pool and climb out on the opposite bank. Take the first path on the right, up the slope and between the rocks, as shown in this screenshot. The document is just ahead on the left. When you're done, climb the rocks to the south, swing over to the plane fuselage, and slide down to the campsite. (Click image for more and larger screenshots.)

DOCUMENT 7 - A King's Ransom (Conquerors)

This document is inside the Crypt of Rimak, The Storyteller. Fast travel to the Plane Fuselage Base Camp then head northwest to the crypt entrance. The document is in small room behind a crumbling wall near the sarcophagus. If you missed it the first time, you can reach it by following the crypt walkthrough. To get back to camp, follow the path in this screenshot. Climb the rocks, swing over to the plane fuselage, and slide down. (Click screenshot to enlarge.)

DOCUMENT 9 - Finger Length Away (Search for the Hidden City)

This document is also in the Underworld Gate Challenge Tomb. If you've already explored there, fast travel to the Canyon Ruins Base Camp. Then follow the tomb walkthrough to reach the document, which is just before the fallen tree you must cross to reach the puzzle area. Once you have the document, you don't need to take the circuitous route past the stele to get back to camp. Instead, exit the alcove with the document, turn right, and follow the path shown in these screenshots to get back to the Canyon Ruins camp. (Click screenshot to enlarge.)

DOCUMENT 11 - Surprise Witness (Metamorphosis)

This document is also found in the Judge's Gaze Challenge Tomb, northwest of the Plane Wreckage Base Camp. The document is in the raised hallway on the southeast side of the ladder puzzle area. Follow the tomb walkthrough if necessary. (Click screenshot to enlarge.)

DOCUMENT 13 - Fawcett's Last Letter (Expedition Unknown)

This document is in the same cave as the treasure chest, above, southwest of the Plane Wreckage Base Camp. You can't reach it until you get the climbing axes. To save backtracking, wait until later in the game when you acquire the lock pick. Then return for the document and treasure chest at the same time. The main walkthrough includes details.

MURAL 2 - Rimak, The Storyteller (Resting Places)

This mural is in Rimak's Crypt. Fast travel to the Plane Fuselage Base Camp then head northwest to the crypt entrance. (Follow the crypt crypt walkthrough if necessary.)

MONOLITH (Proficient Quechua)

There's only one monolith in this level. It's in the drawbridge puzzle area about halfway between the Plane Fuselage and Jungle Ruins Base Camps. See the section for relic #6, above, for details on how to get there and back later in the game. Deciphering this monolith provides the clue to find survival cache #6, below. (Click screenshot to enlarge.)

SURVIVAL CACHE 2

This cache is at the south end of the starting area where Lara retrieves her gear after the crash. To reach it, start at the Plane Wreckage Base Camp and head due south. In the bottom corner of the area, near the tree you climb to reach relic #3 (above), there's an opening in the rocks. The cache is buried on the left side of that opening. (Click screenshot to enlarge.)

SURVIVAL CACHE 4

The next cache is in the area with the pool and waterfalls northwest of the Plane Fuselage Base Camp. If you wade through the pool all the way to the north end, you'll find the cache buried near the rock wall, just below and to the right of the Crypt entrance. When you're done, follow the path in this screenshot. Climb the rocks to the south, swing over to the plane fuselage, and slide down to the campsite. (Click screenshot to enlarge.)

SURVIVAL CACHE 6 (Monolith Riches)

This cache only appears after you've deciphered the monolith, which requires that Lara be Proficient in the Quechua dialect. The monolith is in the drawbridge puzzle area about halfway between the Plane Fuselage and Jungle Ruins Base Camps. See the section for relic #6, above. Deciphering the monolith reveals a clue: "Two serpents guard life and death. I lie trapped within their eternal struggle." Climb the nearby steps to find the cache buried between the two stone serpent heads. Check the main walkthrough for more info. (Click screenshots to enlarge.)

SURVIVAL CACHE 8

This cache is in the Underworld Gate Challenge Tomb. If you've already completed the tomb, fast travel to the Canyon Ruins Base Camp. Then follow the tomb walkthrough. The cache is just before the fallen tree you must cross to reach the dangling crate puzzle. If that's all you need in this area, you don't need to solve the puzzle again. Just exit the alcove where you found the cache, turn right, and follow the path shown in these screenshots to get back to the Canyon Ruins camp. (Click screenshot to enlarge.)

EXPLORER BACKPACK 1

Backpacks are not required for 100% completion, but finding them reveals the locations of other collectibles on your in-game map, so they can be useful. From the Plane Fuselage Base Camp, follow the path down the hill to the west, toward the area with the pool and waterfalls. Dive into the pool and swim over to the little cave ahead on the right to find the first backpack inside. Examining it reveals survival caches #1, #2, #3, #4, #7, and #9 on your in-game map. To get back to camp, climb out on the bank and follow the path on the right. Climb up the rocks, swing over to the plane fuselage, and slide down to the campsite. (Click screenshot to enlarge.)

ARCHIVIST MAP 1

Archivist Maps are also not required for 100% completion, but examining them highlights other collectibles on your in-game map. This one is inside the Crypt of Urqu, The Scout. If you missed it the first time, re-enter the crypt and follow the dark passageway. Just beyond the area where Lara has to squeeze through a gap lined with spears, turn right. Halfway along this passageway on the left is a narrow opening leading into the room with the map. Examining it reveals several collectibles on your in-game map: relics #2, #3, #5, #7, and #9; documents #1, #3, #4, #12, and #13; murals #2, #3, and #4. If this is your first time through, you'll retrieve the map on the way out, as described in the crypt walkthrough. (Click screenshot to enlarge.)
