  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.

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: 2 MORE TO GO

Report submitted by: General FebonioClan

So I have been working with a small group of geocachers to complete the first 6 missions. This is an updated overview of the two trips it has taken to get four of the six missions completed that are all in the San Diego area.

It started with MAGICN3 and I heading to San Diego to start with the three caches closest together. We went to Mt Soledad as it was the closest to us as we headed south and then worked our way back to the north. So we started with BZ A.P.E. 55(a): Supernatural Supernova - this was unique in that the final coords seemed to be confusing as there were two locations. We finially figured out that the Traditional Cache along the nearby guardrail meant that the final location was the Original coords per the log entry and not the posted. We were excited to find the first of thee FBZ A.P.E. Missions and it did not disappoint. The treasure trove of information from the SECRET envelopes to the number of TBs was insane.

Next, we did some Challenge Caches that had been recently published in the area by LaJolla- who can pass up Challenge Caches.

Then we headed southeast to accomplish FBZ A.P.E. 54: Rock River Burial Mound. At first we thought this would require a long hike since the trail seemed to in a gated community. The gate is apparently open all day so we went in an parked at the trailhead mentioned in the description. The rocky riverbed meandered around a bit and at one intersection we went the wrong direction but soon realized our error and backtracked back to head the other way. This was another amazing find. So examined the evidence and took pictures for later and then headed back the way we came.

The last one was actually the one we shouldve done first as it was the longest hike on the day. We enjoyed the hike but with a time limit for our return to OC of 7pm we needed to hustle. That said we did managed to add a few other caches along the way.

After discussing the first three complete missions at an event, there were a few other cachers that wanted to start the A.P.E. Missions. So mpark65 and mike2find went down to San Diego a couple of weeks later and they completed the same three that MAGICN3 and I had previously completed. Once they returned we helped them navigate the site to enter all teh Spec Ops and mission codes into their accounts.

Next we started to plan for the next cache on the list - since it was over a 2+ hour drive just to reach the trailhead. After almost a month, we headed down south to the farthest cache FBZ A.P.E. 52(a): The Bunkers. Here we unfortunately found the cache had been destroyed with only bits and pieces of the evidence left in the bunker. Muggles had apparently used the ammo can as a fire pit and burned it all. So disappointed but in reality felt immensely sad for SGTF as the work on the first three was unbelievable so we were expecting another amazing cache.

The CO was contacted and given a Situation Report- devastated but did give permission for us to log the cache as foudn and thus another completed mission. He further assisted in helping us advance our rank by providing info about the TBs that had been in the cache container.

Now we are in talks to figure out when we will head out to find the last two missions FBZ A.P.E. 51: Stone of the Lost Valley Revisited & FBZ A.P.E. 56: Little Green Men. Hoping to make a trip before the end of September so we can get ready for the FINAL MISSION.

Operation Silverback: My ongoing mission

Report submitted by: General mpark65

I have come down south with mike2find to take on the Apes of socal and the first in the mission was FZB 53. We arrived at the Parking cords and began our trek through the mountains until we arrived at the burial site and explored the contents of the stash box, with a lot of things to look at and info to collect we then proceeded on to the next one which is FZB 54, upon arriving we managed to make our way through the community and up the trail to the next resting place and collected all the info to proceed on the the last one for the day which was FZB 55(a). We made our way to GZ only to find that there was so much paranormal activity they had fenced of the area for further investigations. We then went through some logs to find that we needed to readjust our cords to another location where we found and gathered the info needed to proceed. Turned out to be a great day for alien hunting.

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).
