This area can be reached by going up the muddy slope to the west of the Village Plateau Base Camp. (In the screenshot above, the campfire is directly behind Lara.)

Or, you can slide down the zip line from the one of the ledges north of the vilage. You'll land in one of the two huts, where you'll find pistol ammo, arrows and a salvage crate.

Move outside and open the salvage trunk lying on the ground in front of the tail section of the aircraft.

Then enter the other hut to get a food cache, more arrows, rifle/SMG ammo and a relic (5/6), USMC Dog Tags, from the Semper Fi series. Outside on the little porch is another salvage crate.

Now scramble up the wooden wall behind the first hut.

On the ledge above you'll find a salvage crate and the final statue (10/10) for the Illumination Challenge.

After lighting the statue, move onto the wooden ledge to the left and light the nearest of the 2 hanging burners.

Drop down to the ground and position Lara so the unlit burner is between her and the lit one. Use a rope arrow to swing the unlit burner into the other one, igniting it.

Move to the base of the stone steps below the ledge with the Illumination statue. Shoot a rope arrow into the burner on the right...

...and swing it into the salvage net hanging between the wooden beams.

Now climb onto the roof of the hut on the left.

Use a rope arrow to pull the burner into the other salvage net. Drop down and crack open both crates.
