sgtzara: Owner Check Up 21/09/2016
With the S1 object of this puzzle now gone ... while it's still solvable by some careful googling or examining the past logs of a certain cache, it's not solvable how I originally intended.
On checking the final GZ today, some unusually high tides have impacted on the item at GZ and indeed taken the cache with them.
As this one has changed so much, I'm reluctantly archiving it. Had a look for an alternative hiding place for perhaps a traditional cache at the final GZ but on not spotting any, decided not to bother and thus the final GZ area is freed up for someone else to place a cache nearby if they wish.
