What is this?
Convert the letters of your answer to numbers in the usual way (see below) to get the six digits PQWXYZ.
(The standard letters to numbers conversion is like this:
A = 1, B = 2, C = 3, D = 4, ... , X = 24, Y = 25, Z = 26
If there are any numbers in your clue word, they stay the same.
For example, "benjw1" turns into 251410231.)
The cache is then located at North 52° Q(Z-P).(Y-Q)XZ', East 000° 0W.Y(W-Q)(W+Y-X-P)'.
Please note that the cache was moved on 9 November 2020. The answer to the photo puzzle is the same, but the equations have changed and so the coordinates you get out of them are different. If you solved the puzzle before November 2020, you will have to resolve it in order to get the new coordinates -- but if you can't remember how you did it, then please contact me, quoting the old coordinates, and I'll send you the new ones.
The cache is a small (140 ml) lock'n'lock-style container, covered in camouflage tape.
