The first cache is buried near the low wall just north of the Installation Vista Base Camp. You should be able to spot its flashing light. Check the map if necessary. (Click screenshot to enlarge.)

SURVIVAL CACHE 3

In the part of the Installation Vista with the barrels and abandoned boxcar, where you first learn to use distraction by throwing an empty can, there's a survival cache buried behind the boxes with the yellow strapping. Check the map and walkthrough for details. (Click screenshot to enlarge.)

SURVIVAL CACHE 5

This cache is buried behind the Supply Shack, near the Communications Tower Base Camp. Face the entrance to the shack. Then follow the right outer wall to the far (northwest) corner of the building. You should then see the Interact icon showing where to dig. Check the map if necessary. (Click screenshot to enlarge.)

SURVIVAL CACHE 7

This cache is in the same general area as #7. If you missed it, fast travel to the Gulag Base Camp, squeeze through the gate to the north, go up the hill and through the building shown in the previous screenshot. You'll find the 8th cache buried on the left side of the path just before the abandoned trackhoe. (Click screenshot to enlarge.)

SURVIVAL CACHE 9

This cache is in the Train Yard, but you can't reach it during your first visit. After completing the Gulag and unlocking ROPE ARROWS, follow the walkthrough for The Unlucky Ones Mission, which explains how to approach the Train Yard from the northeast. The satchel is sitting near the outer wall of the main building on the east side. It's also marked on the map. (Click screenshot to enlarge.)

SURVIVAL CACHE 11

The next 3 survival caches are in the Voice of God Challenge Tomb area. Their locations are revealed on your in-game map when you find the Explorer Satchel in front of the tomb entrance. The first of these is buried nearby. See the map and walkthrough for details. (Click screenshot to enlarge.)

SURVIVAL CACHE 13

This cache is on the path leading back from the Voice of God Challenge Tomb, on the ledge just before you slide down the rope line to the second relic. To get it later, return to the Frozen Gorge Base Camp and follow the original route through the canyon, but when you come to the rope line leading to the tomb entrance, don't slide down. Instead climb onto the ledge on the left to find the cache. (Click screenshot to enlarge.)

SURVIVAL CACHE 15

From the Copper Mill Yard Base Camp, go through the gate to the southeast and past the truck and wooden shack. This cache is buried in the corner at the far end of the row of train cars. If you found Explorer Satchel #4 in the cave on the east side of the Logging Camp area (C7 on the annotated map), this cache will be marked on your in-game map. (Click screenshot to enlarge.)

SURVIVAL CACHE 17

This cache is also in the passageway leading to the Red Mine Challenge Tomb. After falling down the mine shaft and sliding into the lower tunnel, continue down the tunnel to the right. A little farther on, the tunnel splits, and this cache is in the dead-end passage on the right. Again, check the map and walkthrough if necessary. (Click screenshot to enlarge.)

SURVIVAL CACHE 19

You will not be able to reach this cache until you discover the Copper Mill Bridge Base Camp, about two-thirds of the way through the game. The cache is buried just southwest of the campfire. See the map and walkthrough for details. (Click screenshot to enlarge.)

SURVIVAL CACHE 21

This cache is buried on a small ledge to the right of the high, wooden wall near the Communications Tower Base Camp. Once you unlock CLIMBING ARROWS, you can scale that wall and then drop down onto the ledge with the cache. See the walkthrough for details. (Click screenshot to enlarge.)
