At the place of the cache there is streaming water that might be tempting, but be careful !
The coordinates N57 46.STU E12 16.WXY have to be calculated according to the formula :
STU = 8*A+2*B-4*C+12 WXY = 5*C-5*B-A-17
The cache is a tiny container but bigger than a nano containing ONLY A LOG STRIP.
BRING YOUR OWN PEN !!
Good Luck !!
