In this position from a proper game of Chess, one black piece
(not the pawn) is actually a white piece (any type) in disguise, on
the same square. This square is also the cache location. There is
only one possible solution when abiding by the Rules Of
Chess.
The 400m x 400m square chessboard is oriented with True North at
the top, and the exact centre of the board is at N45°29.DHL'
W75°52.LEE'
To decrypt these coordinates, you'll need to form a string of
digits by listing the alphabetic positions (A=1, B=2,
..) of each letter in the name of the black piece to form a large
number. Then do a similar trick with each letter in the name of the
white piece, except reverse the final order of digits for the
resulting number.
Then multiply the two numbers together, giving a much larger
number for use as the decryption key. The first digit of this value
represents A, the second B, and so forth.
| For example, if you thought the
incorrect black piece to be the PAWN, and the correct replacement
white piece to be a BISHOP, then the black number would be
(16-1-23-14) 1612314, and the white number would be
(2-9-19-8-15-16) 615189192. Multiplying these two values gives
991878146910288, yielding coordinates of N45°29.840' W75°52.077'
for the centre of the chessboard. |
Once you know which square, and have the coordinates of the
centre of the board, then a little math and a simple waypoint
projection using your GPS should point you to the cache.
The cache was originally a medium-sized tupperware style
container, but got destroyed by several winters and the occasional
animal. The new container is a small ammo can. And, oh yeah,
there's even a nickel in there somewhere!
Fully winter accessible. Shoeshoes recommended by mid-winter (or
XC skis, given sufficient skill on slopes).
Have fun!
