Ideally I would have placed this at a more appropriate location, but sadly I couldn't find one nearby.
The cache can be found at:
N (QV+GZ) (TP-US).(RF+KW-FT)
W (LZ-YT-JX) (LK-KL).(TW-ZP)

It is strongly recommended that you do not approach the cache location from the south west (although I have not checked the route from the other direction), unless you enjoy deep mud or are wearing waders. The approach from this direction would currently deserve a terrain rating of at least 3.5, and although it is often muddy this is the worst I have seen it.
