  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 Orangutan
Geocaching Reference Number TB2JRHA

Worth 10 Points (Create an account to enter TB tracking number and earn points!)

 
POTAM Orangutan Tracking Bug ImageCurrent GOAL:
Your TOP SECRET mission (codename ORANGUTAN) is to further this Special Reconnaissance (SR) evidence through any means possible to help it reach its destination at N 37° 50.758 W 121° 56.068 (GCWBRF), the "Return to Planet of the Apes" California Command Center (formerly Devil's Spoon) in Mt. Diablo State Park.

About this item:
SGTF has obtained a critical piece of intelligence that needs special handling and care. We believe this media disk contains enemy correspondence, photographic surveillance and other important tactical data related to the 2001 Tim Burton film, Planet of the Apes. Per SGTF's AOR under Operation Silverback, operatives to help forward this classified item to the GCWBRF 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!
