The posted coordinates are for the parking lot where you will start this geocache adventure. Mayfield Earthwork Fort is a city of Manassas park, therefore it is open from sunrise to sunset daily. Absolutely no night caching. Off the trail there are a lot of groundhog holes so watch your step.
Mayfield Fort Historic Site preserves one of the few remaining portions of the Civil War fortifications built to protect the vital rail junction at Manassas, Virginia. Covering 11 acres, the Mayfield Fort site is located on high ground between Buckhall and Russia Branches. Both are tributaries to the Occoquan River and strategic point between them was an ideal place for a Confederate fortification.
For this puzzle cache you will
need to visit five signs to locate 4 numbers and four letters. These will be used to locate and unlock the geocache. You will also have to decode the "lock combo" using a CSA Cipher Disk that is on the final container or posted on this cache page. SIGNS ARE MISSING. New puzzle below.
During the Civil War, if signals were to be displayed in the presence of an enemy, they were guarded by ciphers. These ciphers were capable of frequent changes. The Confederate Cipher Disk was a mechanical wheel cipher consisting of two concentric disks, each with the 26 letters of the Latin alphabet, that was used for the encryption of messages. It was created by Francis LaBarre and was based on the Vigenère Cipher.
For this geocache we are using it as a simple substitution cipher as it set on the container at the GZ (or use the same cipher disk as it is set in the picture below). Use the top row of the cipher disk to match up with the coded lock combo below. For instance, if your four letter word from the sign was "LAXF" the cyphered jumble from the disk would be "CROW." Puzzle:
N 38° 45._ _ _ W 77° 27._ _ _
You can validate your puzzle solution with certitude.
Please be gentle with the container and remember to put everything back and lock the container when you are done. If you get stuck, have problems with coding, or want to report damage message me from geocaching.com or email at email@example.com.
