You Wouldn't Believe What Scientists Found Frozen in Glaciers and Lakes

Spears of Iron

It was formerly assumed that Iron was not discovered or utilized until the middle ages, but iron weapons and tools found frozen under the ice in the north have been dated back 500 years before then. Inuit and other ancient societies have shown evidence that they too forged iron, and it was very well done and effective for the time period and the tools that were available. Iron spearheads were considered to be a new invention, and they were formerly credited to the Vikings and European armies.
