Summit Forest - Southeast Side Collectibles - Part 1

Move out of the water into the forest again and turn right (east). Approach the chunk of rusted metal wreckage and look up to spot a salvage net hanging from a wooden platform. Shoot a fire arrow to burn away the net. Then break open the crate and the second crate sitting near the metal junk.

Continue eastward along the south boundary wall. Soon you'll come to a large rock formation with a plank-and-barbed-wire barrier opposite it in the rock wall. Go into the small canyon in the rocks here.

At the end is another mushroom (9/10).

Move back out of the little canyon and climb onto the rock ledge on the right.

The Solarii have "improved" this ledge with wood planks and old airplane parts. Grab the shotgun shells.

Use the rope line to reach the wooden platform off to the southwest.

Turn left and take a running jump to the grassy ledge with the relic (3/3), a Japanese Ceremonial Dagger. Examine it closely for more info and XP. Then drop to the ground.
