*The reference coordinates are not to be used as the cache is NOT hidden there*
As I was creating a jigsaw of GZ some of the pieces got lost and slipped into 3 other caches. Find the missing pieces (images) and you will see the coordinates. I had 3 other buachaill caches open at the time. All I recall is that the GC codes contained a 66, an 88 and a 99 respectively.
