Looks like it was lying in a pool of some kind of chemical with the reverse (Montecello)?, side down since it shows the most damage, the indentions and rippling looks to me like something ate away at the metal at different rates due to composition of the alloy leaving varying degrees of damage, but on the other hand, it could have been a subject of research for an alien spacecraft who abducted some unwitting victim and then tossed it out of the spacecraft as worthless.
