The above Co-ordinates are not exact and are for reference only, you will need to complete the Puzzle below to obtain the correct co-ordinates.
There's right-of-way access to this cache site via a designated entrance beside a closed gate, there is also an area to park your car close by.
Please do not bring dogs onto the site as there maybe horses grazing from time to time.
Please do not post "Spoilers" which might indicate the cache's location in your Logs, as this will ruin the Puzzle and the game for others. However, close-up photos won't do any harm I'm sure.
The Puzzle
Below is a magic number square. What makes this square "Magic"?
Well I'll tell you; the numbers in each row, colum, and main diagonal lines have the same sum (65).
When the square is complete, the entries will consist of the numbers 1 through to 25,
with no duplicate numbers, and as I've already said, the common sum will be 65.

Cache Co-ordinates:
N53° D1. (C1xB3)+(D3xE2)
W006° D1+A5. (E4xC4)+E3
x: Multiple within the brackets first, then add where required.

I have forced a single solution to the puzzle by placing ten numbers in the square, so don't move them.
Good Luck!
