Note that the final cache is NOT at either the listed coordinates OR at the identified grid reference and you DO NOT need to visit either location. Part of the coordinates for the final are included in this cache. You will need to make note of them to find the Final Bonus cache.
A puzzle (part of a 5 cache series in the rural Vale of Glamorgan - North, South, East, West and Bonus) that will test your map reading skills - Remember those big sheets of paper that got soggy and shreaded in the wind and the rain when out in the hills?
The snippet of map below is taken from the 1:25000 Explorer map 151 - Cardiff, Vale of Glamorgan and Bridgend.
Your task is to provide the full OS grid reference for the location indicated in image by the red arrow and input it into the checker below. A correct input will provide the cache coordinates for the final location of this cache which is relatively close by. To assist with the grid references the following link provides an excellent tutorial on how to take a grid reference.
The format required is as follows (including the grid letters). Included are the final 2 numbers for the accurate coordinates.
