  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 E.B.E. Tracking Bug Image
Current GOAL:
Operatives can discover this intelligence (codename E.B.E.) as part of the final classified Operation Silverback mission. The tracking number for this discovery is listed as the CASE NUMBER on the E.B.E.'s toe tag!

Its discovery is worth 60 points towards an operative's rank on this Web site!

About this item:
Its true whereabouts are unknown, but most suspect this small, deceased "big-headed" Grey clone is hidden in an undisclosed location in the mountains of Southern California.

Please do not remove this "resident" from his current location. He is meant for discovery only!

*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.
