@eto94onako povrsnim citanem interneta bi nasao ovo "The wood is not exposed to oxygen as it is submerged in the water and mud and as a result it does not rot. In fact the wood becomes petrified due to a constant flow of mineral rich water around and through it. As a result the wood becomes a hardened stone-like structure.". Sad mozes mirno na šišu, neće potonuti.
