The cache is not at the above coordinates. They are for the Fustin Needle in Hebden Bridge. You might learn something there; but not how to solve the puzzle! The needle does not point towards the cache!

The Cache can be found at N 53° A.B C D W 002° 0W.X Y Z
In example Row 1: Muggles = 16, Cachers = 3, Caches = 6.

Row 2: (Muggles + Cachers) * Cachers = A

Row 3: Muggles / Cachers = B

Row 4: Cachers – (Muggles / Caches) = C

Row 5: Muggles – Caches – Cachers = D

Row 6: (Cachers * Caches) – Muggles – Caches = W

Row 7: (Cachers + Caches) / Caches = X

Row 8: Cachers + Caches = Y

Row 9: (Muggles / Caches) – Cachers = Z
