This is the first letterbox cache of the series. Inside this screw-top cache, as well as the logbook and a few swaps, is a small stamp and an inkpad. These are not swaps, but meant for anyone who finds the cache to use, so please replace them in the cache after use. And if you have your own stamp, we'd be delighted to see it in our logbook.
The cache is not at the co-ordinates given, they are for this seat with a view near the top of Juniper Top.
You have just climbed over 300ft, so have a rest, enjoy the view, then take 81 from your Northings and 85 from your Westings to find Sid.
If there are A letters in Sid's top line.
B letters in Sid's middle line
and C numbers in his bottom line
the cache is nearby at:
N51°(C).(½A)(B-A)(C-C)
W000°(C+3).(B-A)(A-2)(B-A)
But due to a new fence placed across the footpath, a diversion is now needed through a gate 20 metres to your right.
You can check your answers for this puzzle on GeoChecker.com.
Take a note of the clue inside the lid. Then you can use the four clues together from the four caches so far to get the hint for cache number 5 (FOR WHICH YOU'LL STILL NEED SID's A's, B's and C's).
