At this FBZ, you have been provided the 1st of a series of codewords needed to unlock details surrounding the final mission of Operation Silverback. Use SGTF’s cipher to decode secret writings discovered during this and other FBZ adventures.
In all, there are a total of seven (7) caches encompassing this series. Six FBZs contain “intelligence” report(s) and a corresponding secret codeword. Enter these six (6) codewords collectively in the codewords panel at Forbidden Zone Geocaches to unlock coordinates to the seventh and final TOP SECRET FBZ location. Keep in mind that codewords can be gathered in any order so you DO NOT need to visit FBZs sequentially!
At this TSG you have been provided with a piece of “ancient” shale rock which will direct you to a nearby shaman burial spot where you can discover the first mission codeword for Operation Silverback (UPDATE 1/16/16: codeword has been relocated to the ammo can). Use the "pig-pen" or masonic cipher to help decode the symbols on the rock and all subsequent secret writings you find during your participation in SGTF’s black project (a.k.a. “The Activity”).
FBZs are reserved for POTAM related to SGTF's Silverback operations. Visitors are encouraged to register their visit and leave ONLY items containing relevance to The Planet of the Apes or items that are traditional hitchhikers (e.g. geocoins, travel bugs, etc.).
