Geocache Description:

Something a little more challenging...

The cache is not at the given coordinates. There is no need to go there. It is within a few kilometres of them though.
To find the coordinates: the degree values are the same as those given, but you will need to work the values for the minutes out given the following equation. I suspect this will take a bit of concentration - especially if you haven't done much mathematics lately.
Take care retrieving and replacing the cache. You may find you may need some extra equipment to retrieve it, depending on how you get there. It may take a couple of visits if you do not have that equipment with you at the time. Do not retrieve it if you cannot safely replace it. Please take appropriate safety precautions.
