The cache is obviously NOT at the published coordinates or this puzzle wouldn't be a puzzle.
The published coordinates are actually for WP4 to avoid any proximity issues with other caches in the vicinity. However you should plan to start from WP1 (see below) where there is plenty of free parking.
All of the waypoints are either on or very close to well maintained paths through the park. There are no caches at any of the waypoints, just information to be gathered.
Unless otherwise stated the information you gather at each waypoint will take the form of either an initial letter of a word, or a number. Where it is a letter you can convert to a number using a=1,b=2,c=3,d=4.......i=9,j=0,k=1 etc.
Waypoint 1 N51 24.992 W0 43.504
OM= Month the Earl and Countess of Wessex opened the park following its restoration (where Jan=1, Feb=2 etc)
Waypoint 2 N51 24.925 W0 43.499
WC= Which Country does some of this wood come from?
Waypoint 3 N51 24.934 W0 43.585
BD= Built around?
Waypoint 4 N51 24.929 W0 43.639
HP= What historic period is this feature typical of?
Waypoint 5 N51 24.886 W0 43.660
NM= What number is this pond?
Waypoint 6 N N51 24.833 W0 43.571
TS= How does it taste?
Waypoint 7 N51 24.821 W0 43.445
UP= How many vertical uprights support the roof?
Waypoint 8 N51 24.881 W0 43.342
SL= How many slices of tree above and around?
MW=Which motorway (M?) gets a mention?
Gather all of the above elements and substitute them into the equations below to get the coords of the cache.
N = 51 (OM*NM). (MW*WC)(WC)(UP/WC)
W = 00 ((HP*TS)-WC).(BD- ((UP*(SL+MW)*WC)-HP)) / HP
The cache and all waypoints have been intentionally placed/chosen either on or very close to a path to avoid any impact the caching traffic may have on the park.
You are looking for a micro cache (screw top specimen jar) containing a log and a pencil.
Bonus Cache:- Having walked around the park and found this cache it would be a shame not to find the other cache "Hidden Jems One" that's also hidden in the park and which is very mini-cacher oriented. The listing for that cache can be found by following this link: Hidden Jems One
