This is a series of 10 caches leading to a bonus cache. All the caches are located in the north of Sheffield city centre, where there was a big gap on the geocaching map, and I couldn't resist filling it! While some of the caches are micros, there are no nanos in the series. Not all caches have a pen so you will need one, and tweezers would be useful for some.
Please see North Sheffield Series - Bonus for full details of the series and the clues.
This cache includes clue Z - a three digit number. In order to find this cache, you will need to go to the listing coordinates and pick out some details from the nearby information. While you're here, check out Well, it's art innit? - an interesting local cache.
The question you need to answer is when was this furnace last used? The answer is ABCD.
Once you have found the answer, use the details to complete the following coordinates:
- N53 23.[(A+B)/C] [A-D] [B-A-D]
- W001 28.[B-D] [D-A] [C]
The cache will be located here. Good luck, and don't forget the clue for the series!
