This is a multi that requires a little logic thinking-solving along the way.
At the starting coords, you will find a clue. Convert that clue to a number. Example: If one of the clues is a "boat", then the number would be 2. One of the clues will not work this way though, so look at the hint for that.
Now continue walking south from GZ and see if you can find more clues. Do you see them? You are looking for a total of 6 clues. The first 3 are for the North Coords. The last 3 are for West.
Even though the stages are listed as waypoints, just set them aside for the moment. You should be able to find the clues easily enough without looking at the stages
Easy stuff! It shouldn't be too hard. 
Send me an email if you get stuck.
Checksum for the 6 clues is 25. Also: apologies about the stickers/foxtails in this area! Be advised.
