The cache is NOT at the posted
coordinates.
This is a permanent cache, it was placed for the CCARF11 event,
held October 22-23, 2011 and remains in place.

Step #1: The Mathdoku
The first step in finding this cache lies in solving this
Mathdoku puzzle.

The rules for the puzzle are easy:
- Use only the digits 1-4
- Each row contains exactly one of each digit with no
repeats
- Each column contains exactly one of each digit with no
repeats
- Each bold-outlined group of cells contains a clue with a number
and symbol. The symbol represents the mathematical operation and
the number represents the result. For example, if the clue for a
group of 2 blocks is "5+", some possible answers could be 1+4 or
2+3
Step 2: Produce the Final Coordinates
Once you've solved the puzzle you can use that to come up with
the final coordinates for the cache...
N 51° 09.[I-O][E+L][D] W 114°
11.[E+K+H][B-P][A+J]
You can check your answers for this puzzle on

Step 3: Find the Cache
We'll assume everyone is comfortable with this part of the
process :) We recommend starting at the indicated parking point.
From there you can follow the pathway toward the cache until the
pathway ends (park still in progress). Follow the foot trail
straight ahead about 40m until it intersects with the other walking
path. From there you follow the path up and cut straight across the
field to GZ. And be careful. There are a lot of burrs along the
way.
Step 4: Open the Cache
To open the cache you'll need to solve a simple math puzzle in
the field. If addition is not your friend, you may want to drag
along a calculator.
