Ark Chests
1. Ark Chest
From the entrance to the ark facing southwest, head forward and use the metal crates near the southern wall to jump over it to reach a long ramp. (If you completed the ark, the wall will explode allowing you to just walk through it.) Follow the ramp down and head north along the dirt road to come to a ruined structure. The chest will be located on the north side of the structure past some metal crates.
2. Ark Chest
From the previous chest, head south out of the ruins and follow the dirt path until you are halfway to the ramp. Take a right and head southwest towards a machine with three propellers slighting spinning on top. When you reach the machine, head west into an open courtyard to find the chest sitting next to some metal containers. A radio tower will be in the center of the courtyard.
Storage Containers
1. Storage Container
The container is located next to metal containers on a ramp heading down on the west side of the ark.
2. Storage Container
From the previous container, head northwest down the ramp and go behind the metal containers on the right to find the storage container.
3. Storage Container
From the previous container, follow the dirt road northwest into a ruined structure. From the entrance take a right heading into an alcove under a ledge to find the container next to some metal crates.
4. Storage Container
From the previous container, exit the room and jump up to the ledge above. Follow the ledge around heading north to reach the container near some metal crates.
