Where can the Message in a Bottle appear in Roshamuul?

Question

During my hunt in Roshamuul I saw few times Message in a Bottle   in two different places - never same places. I found information about achivement called "Nevermending Story". You can gain it for catching 11x Message in a Bottle by using fishing rod . 

My question is: 

Where can the Message in a Bottle appear in Roshamuul?

Answer 1

After catching 11 bottles you have to go dig a hole and use a skeleton to get the achivement. 

The place is in this area:

Note : If you don't find a bottle, it's probably on Mawhawk's Lair.
