Geocache Description:

Please make note of additional waypoints published for this cache. Operatives will discover a ciphered message at GZ which directs them to the top secret mission 54 codeword location (2FBZ54).

At this FBZ, you have been provided the 4th in a series of codewords needed to unlock the final mission location for Operation Silverback. Use SGTF’s cipher to decode secret writings discovered during this and other FBZ adventures.

In all, there are a total of seven (7) caches encompassing this series. Six FBZs contain “intelligence” report(s) and a corresponding secret codeword. Enter these six (6) codewords collectively in the codewords panel at Forbidden Zone Geocaches to discover the seventh and final TOP SECRET FBZ location. Keep in mind that codewords can be gathered in any order so you DO NOT need to visit FBZs sequentially!

Mission Details:
SGTF has decided to place a Forbidden Zone (FBZ) in what we assume to be a hallowed simian burial mound along the banks of an "ancient" river bed in the wilds of Mission Valley. SGTF believes this TSG may help flush out dangerous primates who are lurking deep inside MV's canyons.

Sandrock Canyon (SRC) is a known hotbed for paranormal activity.* There have been peculiar sightings of abandoned encampments along the now dry river bed and an unexplained mystery surrounding the discovery of small, dimpled spheres (resembling golf balls) in a specific zone near the FBZ. The closest golfing course to A.P.E. 54 exists 4.63 kilometers (2.88 miles) to the southwest, and a driving range is located 2.02 kilometers (1.26 miles) to the northeast, but neither location can be considered close enough to be the source of the small spheres which inexplicably continue to gather on the floor of the canyon. It is a mystery which has baffled SGTF’s scientific community. Originally, there was speculation a nearby homeowner might be driving golfing balls off the back of his deck into the canyon, but the theory was soon discounted after SGTF decided no person in their right mind would be stupid enough to participate in such an idiotic, destructive and shameful activity. Humans are much smarter than this.

SGTF is convinced an intelligent primate species occupied this canyon centuries ago, and hypothesize the mound where this TSG is located was likely a tumulus or cairn where ancient primates cremated and/or buried their ancestors. In fact, a local archaeologist unearthed an anthropological relic nearby which bolsters this theory. SGTF has managed to obtain this specimen through our underground network and included it as part of the FBZ A.P.E. 54 Top Secret Geocache (TSG).

At this FBZ, you have been provided a rock painted with secret symbols that will direct you to a nearby location where you can pay homage to this fascinating anthropological remain. You will also be provided the 4th in a series of codewords needed to unlock the final mission location for Operation Silverback. Use SGTF’s cipher available at to decode secret writings discovered during this and other FBZ adventures.

FBZ A.P.E. 54 contains an ammo can with Special Reconnaisance (SR) related to SGTF's Operation Silverback in the form of Planet of the Apes Memorabilia (POTAM) and scouted intelligence reports. As a clandestine special tactics unit, SGTF has been known to leave POTAM tracking bugs in their FBZs with operative mission instructions related to active Project A.P.E. caches.

FBZs are reserved for POTAM related to SGTF's Silverback operations. Visitors are encouraged to register their visit and leave ONLY items containing relevance to The Planet of the Apes or items that are traditional hitchhikers (e.g. geocoins, travel bugs, etc.). Only place and/or remove TRACKABLE items from this cache (read NO unrelated SWAG); Any POTAM found in this cache designated as NOT TRACKABLE is pertinent to operations for this FBZ and should REMAIN ASSIGNED TO THE CACHE. POTAM labeled PROVISIONAL FTF is considered remittance as reward for the FTF (First to Find) and can be removed freely without restriction or stipulation.

*Disclaimer: Stories here and at FBZ cache sites are mostly fictitious. Any similarity to any event, group, or person living or dead is merely coincidental.
