Only Connect #8 Mystery Cache

This is the latest in the series started by Jesmond Lynam who is happy for me to contribute this cache.

The cache isn't at the published co-ordinates but it isn't too far away. There is parking not too far from the final co-ordinates. You will need to supply your own pen or pencil to sign the log.

To find the cache it is necessary to identify what the connection is between the four pictures and perform a couple of short calculations to find the co-ordinates of the final cache.

A = the number of letters in the word linked to photograph A.

B = the number of letters in the word linked to photograph B.

C = the number of letters in the word linked to photograph C.

D = the number of letters in the word linked to photograph D.

E = the number of letters in the connection between the four photographs (two words, the second one plural).

Y = (E+A)*(C-D)

Z = ((E*B)+A)*(C-D)

The cache has been placed at: N54 56.Y W001 35.Z
