This is the third in my occasional pond series (the first two being Normandy Pond and Cutmill).
After receiving reports, I decided that Cutmill was perhaps a little too difficult. So to redress the balance, this one is much easier.
Near the pond is another water-related feature.
Find the horizontal piece of wood with holes drilled through, and count the holes.
A = number of circular holes
B = number of square holes
To find the cache you will need some offsets to add to the dummy co-ordinates at the pond:
N = (A-B)*D*G
W = (D*H) - (A*E)
The cache is a 35mm film canister micro.
