The above co-ordinates are for nowhere in particular.
The co-ordinates for the cache are hidden in the maze on this web page:-
See the Instructions link to learn how to navigate the maze. You might also consider looking at the 'Tip' link. The challenges in this maze require you to get out and about (twice!). Collect the first seven locations from the maze, then go visit them to collect the information requested. Having penetrated the first line of defence you need to collect a further seven locations and visit these for yet more information!
The locations are numbered, but this is just a suggested collection order. Part of the challenge is to work out the optimum way to visit them all. Google maps and/or a good Ordnance survey map would definitely be of benefit.
If you take the routes I'm nudging you toward, both worthwhile walks in my opinion, then the first excursion passes not so far away from three of Cache U Nutter's 5*/5* caches and the second takes you past a further four Cache U Nutter caches and with only minor detours you could pick up a couple of dwarves (by sadexploration)! You will also, at some point along the way, have passed within 10m of the cache site.
The cache does not contain a pen nor pencil - please bring your own writing implement. The log sheet is to be found in the specimen screw top pot, where hopefully it will stay dry.
