This guide reveals the location of all 64 junk items you can find on the islands.

Since this is not a walkthrough, I've chosen to reveal the relevant information according to the junk inventory in rows and columns. Locations are given in two separate sections:

• Island Indicator
  This one will only slightly spoiler your search because it merely indicates what island each junk item is located on.
  
• Rows 1 - 8
  There are sections for each row of the inventory with spoiler-hidden screenshots of the junk location on the relevant map. Use at your own peril!

Note that this guide does not provide screenshots of the precise dig location given that Drayton will help with those. However, you may notice that some loactions are impossible to reach with Drayton ... at least for the time being. Rest assured that once Drayton gathers more experience you will be able to get him where he needs to be.

Happy puzzling!!!

PS: Should any image be missing (as it happens frequently, lately, with Steam guides) please notify me in the comments. I'll try to fix that issue then.
