  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 Zira Tracking Bug Image
Current GOAL:
Your TOP SECRET mission (codename ZIRA) is to further this Special Reconnaissance (SR) evidence through any means possible to help it reach its destination at N 47° 23.514 W 121° 27.305 (GC1169), the "Project A.P.E." Mission 9 Tunnel of Light Command Center.

About this item:
SGTF speculates this furry luggage tag was distributed to promote the 2001 Tim Burton film, Planet of the Apes. Per SGTF's AOR under Operation Silverback, operatives to help forward this materials item to the M-09 TOL cache for further exploration have begun.

Please do not keep this TB if you DO mistakenly remove it from the Project APE cache. Drop it in a cache somewhere for another person to find and perhaps the mission will be completed again!
