Hello there!!!
this is the first thing that came to my mind when you said that it was iron and you found it at or in the lake
Why is it not rusted?? I read this from Earth Forbidden Secrets many years back.
A Pillar of much too Pure Iron
In Delhi India there is an Iron Pillar that has completely defied metallurgists by remaining
absolutely rust free for the last 1600 years, ever since its discovery by the west
(fig.45). It’s
unclear for how long the pillar has actually been standing for
(in fact there is more than one of
these in India) but the problem lies in the fact that such rust free iron, of the type that is found in
these pillars is unheard of in our modern technology.
These iron pillars are in fact a metallurgist nightmare, or dream, depending on your mindset,
but
one truly interesting thing is the fact that the only other place completely rust free iron has
been located, is in rock samples that were brought back from the moon during the Apollo
missions!
I am M...Y....S....tified?
