Pipeline Project Makes Unintentional Historic Find

It's being called one of the biggest infrastructure improvements for the nation in 25 years but as the 1,700 mile Rocky Mountain Natural Gas pipeline winds into the Tri-State, it's making history in a way no one expected. Archaeologists said that what excavators found near Brookville, Ind., is so significant that it could help rewrite history books.

The workers uncovered what seems to be evidence of an unknown previous settlement that dates back thousands of years.

Some of the evidence that have been uncovered so far dated back 600, 1,000 and even 5,000 years old, archaeologists said.
