Shantytown - pickups Near the Oily Pool Beyond the Ancient Gate

There's a GPS cache flashing away in the corner of the fenced-in area on the left, but you can't reach it yet. For now, drop down onto the wooden ledge below that fence...

...and follow it around to the left. Use the shotgun to destroy the planks nailed across the doorway.

Enter to find a document (4/5), an excerpt from the Diaries of a Madman, plus some shotgun shells.

Exit the room and vault over the railing into the muddy area below. Crack open the salvage crate.

Then shoot a fire arrow into the salvage net hanging in the corner above and to the left of the red helicopter. Break open the crate that drops out.

Turn and look across to the opposite side of the oily pool. There's an effigy (6/5) mounted on the west wall.

NOTE: You only need to destroy 5 of these effigies to complete the Laid to Rest Challenge. If you missed any in the first part of Shantytown, there are several more in this area to help make up the difference. Shoot a fire arrow at the effigy to burn away the cloth. Then pull the post down with a rope arrow.
