  Silverback Cipher  
 
Silverback hunters should be familiar with the “pigpen” or masonic cipher, which is a simple substitution cipher exchanging letters for symbols based on a grid.

This cipher can be used to decrypt directions and secret codewords at FBZ geocaches!

POTAM Nado Tracking Bug ImageCurrent GOAL:
Your TOP SECRET mission (codename Nado) is to further this Special Reconnaissance (SR) evidence through any means possible to help it reach its destination at S 24° 15.967 W 048° 25.299 (GCC67), the "Project A.P.E." Mission 4 Southern Bowl Command Center.

About this item:
SGTF speculates these five Pepsi cola caps are promotional items from the 2001 Tim Burton film, Planet of the Apes that were originally distributed in Japan. Per SGTF's AOR under "Operation Silverback," operatives to help forward this materials item to the M-04 Southern Bowl A.P.E. cache for further exploration have begun.

*Disclaimer: Stories here and at FBZ caches are a combination of historical conjecture, anecdote and pure fiction. Any similarity to any event, group, or person living or dead is merely coincidental. Additionally, SGTF has utilized a variety of signs/stickers as props in the FBZ geocaching series. Labels or warnings (e.g. biohazard, radioactive, etc.) which are fictitious will display some form of the SGTF/Silverback moniker; all other warning signage encountered during this or any other FBZ adventure should be respected and observed as posted.
