Geocache Description:

Westhorpe is one of the 4 communities which make up Killamarsh in North East Derbyshire. There was a colliery in Westhorpe until 1984. Killamarsh was mentioned in the Domesday Book as Chinewoldemaresc which means “Cynewalds Marsh”.

This bonus cache is placed at N53 18.nnn W001 19.mmm, where mmm and nnn are 3 digit numbers.

They may be calculated as follows...

nnn= ((A x B) + E) x (C + A) x (E - D)
