ARCHIVIST MAP 1

This map is in a secret room beneath the floor of one of the ruined buildings on the east side of the city. Climb the bell tower near the building with the second mural. Then use the crank along with a rope arrow to open the trapdoor in the next building so you can reach the map. See the walkthrough and level map for details. (Click screenshot to enlarge.)

ARCHIVIST MAP 3

This map is in the northern section of the city. Just before you use the golden bucket to break the ice and climb up to the second trebuchet, scramble up the wall on the left to find the map. If you missed it, you can get back to the trebuchet from the Citadel Plaza Base Camp. If you pulled down the rope barrier from the other side, you can take the shortcut shown here. Otherwise, follow the Part 2 walkthrough. (Click screenshot to enlarge.)

EXPLORER SATCHEL 2

The other satchel is near the third trebuchet. While you're freeing the machine from the ice, you'll climb up to a tower with a large, wooden bucket. The satchel is behind some debris near this bucket. If you missed it, return to the Citadel Plaza Base Camp and retrace the route in the Part 2 walkthrough to get back to the second trebuchet, then the third. Get the satchel and then return across the rooftops to the base camp. This satchel adds the locations of caches 1, 2, and 6 to your in-game map. (Click screenshot to enlarge.)

SURVIVAL CACHE 2

This cache is buried near the eastern city wall, about halfway between the building with mural #2 and the Challenge Tomb entrance. It's near a broken down wooden wagon. Here Lara is approaching from the south. (Click screenshot to enlarge.)

SURVIVAL CACHE 4

This cache is buried in the corner right next to the Geothermal Cavern Base Camp on the way to the Chamber of Exorcism Challenge Tomb. (Click screenshot to enlarge.)

SURVIVAL CACHE 6

The last cache is buried near the western city wall just south of the first gate. There's a stump with poison mushrooms and a puddle of oil nearby. (Click screenshot to enlarge.)
