The true cache location is given by North 50 AB.CDE West 000 FG.HJK where
A = 144 - 108
B = 120 - 108
C = 140
D = 120
E = 156 - 120
F = 162 - 156
G = 108
H = 150 - 108
J = 108
K = 135 - 120

The cache container is a new design which has just appeared on the market.
A black screw-top pot measuring about 150 mm dia x 50 mm high, it makes a perfect alternative to the horrible 35 mm film canister.
As well as a log book and pencil, it has enough room for small swops, small TBs, and Geocoins
