Bottomless Pit "something that seems to have no limits, or a situation that will never end"
Placed for no other reason than a bit of fun, cache will be found at ground level.
If you enjoy caches that are different then why not visit some of my others locally, like "The Camo Box" A multi which currently boasts a 100% FP record or the "W2H Series" which is a 4 mile circular of 13 unique caches beginning at Wyton on the hill and takes through the beautiful village of Houghton.
