The published co-ordinates are not where this cache is located. In order to find the cache, you will need to complete the series associated with it and collect bonus-related data from the labels in the logbooks. There is redundancy built into this bonus data so that if one or another cache is temporarily unavailable, for whatever reason, you will not be deprived of the opportunity to find this Bonus cache. Each 'set' of 3 caches (e.g. 1-3, 4-6 etc.) will hold the same Bonus information, so, if you forget to make note of a bit of data or can't find a cache, no need to panic! There will be a further opportunity to collect the same information.
When you have collected the 10 pieces of data you require, you will need to substitute the numerical values, associated with each of the following letters, in the formula for the final co-ordinates provided below. The letters are: A,B,C,D,E,F,G,H,J and K = ?
N 51° (J-D).(B+C)(H-J-F)(K-G) W 000° 2H.K(E-A+F)C
This series has been laid out in what can loosely be described as a figure of eight, making possible its division into 2 walks in case some of you don't have time to do all 31 caches in one outing.
Food and drink are available nearby.

Note: you will find it difficult to satisfactorily complete this series without reference to the Hint.
