  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!

Forbidden Zone Geocaches

OPERATION SILVERBACK is a geocaching series created by the Simian Guerrilla Task Force (SGTF) consisting of seven (7) Top Secret Geocaches (TSGs) hidden in and around San Diego in Southern California. It draws inspiration from Project A.P.E., the geocaching promotion introduced by 20th Century Fox prior to their release of the "blockbuster" Planet of the Apes remake in 2001, The X-Files and other science fiction classics.

Authentic Planet of the Apes Memorabilia (POTAM) has been stashed at some FBZs and has also been sent on Special Reconnaissance (SR) missions to various current and former Project A.P.E. cache locations around the globe.

Project APE geocoin iconSome FBZs also include printed images of prized Project A.P.E. geocoins which can be discovered and logged via their corresponding tracking numbers. GC members who enter the TNs will add instances of the ape face icon to their online profiles!

Operation Silverback is the code name for SGTF's self-assigned Intelligence Support Activity (ISA). We purport a link between extraterrestrials and primates and strongly adhere to the notion that aliens are planning to unleash an imminent attack against mankind using an Alternative Primate Evolution (A.P.E.).* We believe our role is to collect "intelligence" related to our assumption and present documentation to its effect.

In our TSGs we provide "top secret" reports and relevant evidence to prove our hypothesis. In addition to these materials, a codeword is hidden at each FBZ that can be deciphered using the Silverback Cipher and entered here on the codeword panel to reveal coordinates to the final FBZ mission, a remote TOP SECRET Forbidden Zone where the "truth shall be revealed!"  Operatives must gather and enter all six (6) mission codewords before they will be able to view the final mission coordinates.

Optionally, operatives are welcome to create an account on this Web site to display their progress as they visit TSGs and successfully enter corresponding Operation Silverback codewords. Points and a special command ranking are assigned to operatives' profiles for correct submissions and other relevant operation engagements.  Keep in mind that codewords can be gathered in any order so you DO NOT need to visit FBZs sequentially!

Operation Silverback: mission accomplished

Operation Silverback

Operation Silverback
Report submitted by: General oesteado

Immediately upon exiting the vehicle, an alien presence could be strongly sensed, almost overwhelming so. Approaching the forbidden zone on foot, anxiety grew with every twist and turn. Yes, the Apes had been here and left totems to warn against human encroachment.... Only extensive Terrestrial Defense Force (TDF) training allowed me to maintain sanity while examining the repulsively fascinating evidence. Mind blasted by the horrific implications, I wandered back to civilization hoping the SGTF possessed the operational fortitude to combat this planet-threatening menace...!

Operation Silverback: Monkey's Triangle compromised

Operation Silverback

Operation Silverback
Report submitted by: General oesteado

Unfortunately it seems that nefarious agents of the enemy have been diligently working to disrupt Task Force plans. Fortunately I was able to maintain contact with a high-ranking SGTF operative who conveyed crucial intel at each location, allowing the quest to continue.... But at the final stop, I witnessed incontrovertible confirmation of an alien connection. And it is my firm belief that extraterrestrials (or their earthly cooperatives) have absconded with damning materials detailing their sinister involvement. Ordered to log a successful find despite my abject failure to find anything useful, it is this agent's humble recommendation that further investigations be suspended until superior officers can unravel the mysterious disappearance of all evidence....

Simian Guerrilla Task Force

SGTF operates in support of the Intelligence Support Activity or ISA (“The Activity”) known under the code name Operation Silverback. Those who claim knowledge say SGTF’s primary objective is to conduct top secret operations in tribute to the spirit of geocaching as introduced in Project A.P.E. It is believed that the SGTF's primary Area of Responsibility (AOR) is to operate as a forward scouting and surveillance team conducting Special Reconnaissance (SR) in relation to materials acquisition including the search and recovery of Planet of the Apes Memorabilia (*POTAM) for emplacement in top secret geocaches (TSGs) named Forbidden Zones (FBZs).
