Geocache Description:

This is a puzzle cache in two parts. Firstly you have to work out the coordinates of the cache site. Once you have done this your next (and possibly hardest) challenge is to locate the cache container itself.

The title of this cache gives you the entire clue you need in order to solve both parts of the puzzle. Good luck!

The cache is NOT located at the coordinates above. These represent a suggested parking spot in the vicinity of the cache. (It is within a 1km easy level stroll from here. The dead-end track/lane through the hamlet of Foul Anchor is very quiet, but please do exercise all due caution on what is after all a public road.)

An alternative equally accessible parking location is the same as provided for our other local cache ‘Gets My Gote’ (GC13N0X) at N52°44.238, E000°08.885. (Your walk from here takes you along the public footpath running along the grassy bank of the North Level Main Drain. The footpath remains well away from the water, but once again please take due care.)

To discover the cache coordinates, you must identify an 11-digit number (ABCDEFGHIJK). That's all there is to it. Think laterally!

When you have identified this number, use the substitution formula below to work out the precise location of cache hiding place:

N5(A+2).(B+2)(C+4).(D-5)(E-2)(F-3) E000.(G-6)(H+5).(I-1)(J)(K+2)

N 5___ . ___ ___ . ___ ___ ___ E 000 . ___ ___ . ___ ___ ___

So, you have arrived at the cache coordinates? The following might give you some help:

The cache container is hidden in plain sight.
It is not at ground level.
You do not need to touch, move, disturb or otherwise interfere with ANY vegetation to see the container. It's there, so PLEASE do not cause any damage.
The best advice is simply to look for something that is ‘not quite right’.
Have patience and you will be rewarded!

Once found, please do not remove the cache container from where it is has been fixed - simply gently remove the log (you’ll know how), initial/date it (bring a pen) and carefully replace.
