You are in the right place if you have found aproximately 100m3 of concrete(a little bit of imagination is also needed). Where the skeleton lays there is no cache.

Cache is in a 0.9l plastic container (size ~10x20x4).

At the moment of hiding cache contained a pen, 2 pencils, an ereaser, a pencil sharpener, donoteat, instructions, a log in a 'minigrip' and some items for exchange.
