Geocache Description:

A 3-stage multi-cache containing one virtual and 2 physical caches.

This is the first in a series of caches to be based around cryptography. The coordinates given for the cache will take you to the first stage of the multi-cache. Located on trails behind Saint Michael's College, it's a nice walk on good trails. The cache is a recycled aspirin bottle and contains nothing more than the coordinates for stage two of the cache. The trails branch off onto what looks like Camp Johnson property, though they are well used so perhaps nobody minds. The cache was put on the public part though, just to be sure.

Upon arriving at the stage 2 location, you'll need to determine the name of what was undeniably the fastest of the vehicles parked there. If you have the time, and it is open, there is a small museum nearby as well. Note that this stage and the final clue may well require some research on the web!

Once you have the name, you have the keyword to decrypt the following clue. This clue was encrypted using a Vigenere Square, which can be found in one of the images included here. A Vigenere cipher is quite hard to break as it can use up to 26 individual cipher alphabets, though it can be manually broken using statistical and frequency analysis.

The final location may be difficult to find and can be a challenging walk depending on your fitness level. Be careful of some downed barbed wire fencing at points along the way and the trails can be slippery in spots.

The cache is a Rubbermaid container and contains a Where's George dollar, scratch-off lotto ticket, hanging sign with witty saying, plastic frog, squirt gun, deck of cards, airplane puzzle, a little smile guy, a shot glass mug, logbook, pen, pencil and a disposable camera. Please take a shot of yourself if you like and I'll have them developed once it's used up. Be sure to log your frame number!

Here's the final clue:

Find...

  • The Road In to Stage 3This is the road that leads back into the snowmobile trails that run through the area. You can follow this road for a while before needing to go off-road.
  • A great viewThe view from near the cache is great, particularly with foliage peak approaching. It's a nice reward for the walk!
  • The Vigenere SquareThis is what a Vigenere Square looks like. It basically provides 26 cipher alphabets and the keyword tells you which row to use as you decipher each letter.
