Challenge: "Ghost Hunter" (Coastal Forest)

Challenges is a side tasks in game. They not required to complete storyline, but can give you extra xp and fun. But they required to finish game on 100% and to achieve "Inconceivable!" achievement.
I wrote this guide because items, required to complete challenge, is hard to find and they not marked on map, unlike other tasks.
I split a guide on locations, because if write everything in one pass, it will too big. Maybe I combine everything into one later.
Items are listed in the order, which they are encountered throughout the game. Of course you can always go back to the desired location and to find the missing items.

Challenge: Ghost Hunter.
Location: Coastal Forest.
You need to find totems, hanging in different places of this level, and destroy them by shooting. There is 10 totems and you need find and destroy them all.

This level separated on two locations: before and after bunker, which contains five totems each.

You slided to this location without any weapon. Before bunker you need find a campfire, find a bow, kill a dear, return to campfire and after all go to the bunker. You can start destroy totems right after you find a bow.

Once you've taken a bow, take a look at the tree on which hung the corpse. On the other hand there is a short branch on which hangs a totem.

This is the first totem, which you can see at this level. Unfortunately for the first time you will not have any weapons to destroy it. You need to take a bow and go back to the very beginning of the level.
Once you have taken the bow, return to the campfire, crawl under the rock and look at the tree in the corner of rock and precipice. Totem is hanging on him.

Go down the creek to a small waterfall and a huge puddle, which creek flows into it. To the north of the puddle there are log spill over between two rocks. Totem hangs right under that log.

Go to directly south of the puddle. You find a rock on your right hand and a tree, growing beside of this rock. Totem hangs on the south side of that tree.

From south east side of valley you can see this and next totem both. You just need to look at west. If you cant, then you should go south-east corner of valley.

From previous point go to west until you find another rock. Totem hangs on the south western side of this rock.

After you pass underground passage, you will get on north part of valley. After you leave bunker you need meet you crew, find Dr. Whitman, collect salvage, upgrade your axe and help Whitman open gates. You can start destroy totems right after you awakes, but before you open the gate.

After campfire go down the stairs and go near left cliff. On that way you pass a second creek. Soon you find Buddha statue, which stands on the raised ground.
Totem hanging at left side of the roof, that cover statue.

Go back until you find a creek. Then go up the creek until you find a bridge. Totem hanging on tree, growing at left shore (a far shore, if you came to this place from campfire).

From this point you can see next two totems. If you cant see them, then follow guide.

Go under bridge, which you just find. Totem hanging under this bridge.

Continue your way up the creek. At the east side you will find a broken bridge. Like a previous, totem hanging under this bridge.

Go north until you reach place, where you need to assist Dr. Whitman open the gate. On the right side of gate is a small building. Totem hanging on the right side of this building's roof.
