I'm amazed at how paper still hasn't degraded after all those years/decades underground, when it comes to the E.T. Atari game landfill that was recently unearthed sure a lot of the papers and card boxes were very crushed but not degraded, but that was in a dry desert with not much rain. So I always assumed that anything of paper or card for that long underground in THIS country, with so much rainwater seeping into the ground that surely it would have easily broken down after this long, but obviously not and that surprises me.
This will be an amazing find of biblical proportions if this gets unearthed, it would be an exciting thing to witness!
