Follow the stream downhill. When the path splits, bear to the left. (The stream goes right.) On a rock ledge on the left are some more arrows. Grab them if you need them and continue downhill, beneath a fallen tree and past an upright tree with rope wound around it (circled in the screenshot above).
When you come to a small hill with a pond below, look to your left to spot another totem (3/10) hanging below a fallen tree trunk connecting two high rock outcrops.
Note that there are a few items up on the ledge at the left end of the fallen tree: more arrows and a salvage crate.
Shoot the totem for the challenge.
If you want to grab the arrows or take a look at that salvage crate now, go around to the right end of the rock formation.
There you will find a series of climbable ledges.
At the top, walk across the fallen tree onto the ledge with the goodies. The crate is of no use to you now, but you may want to return here later when you get the gear needed to open it.
