Deep-Earth map reveals a lost U.S. continent | Science | AAAS

This is kind of a cool story about how an array of sensors have been put to use, and once scientists reviewed the data, they have concluded that there is a piece of a continent jammed under the eastern seaboard of the US. 

Their modeling suggests that this happens when Pangea was broken apart, and this is why we have some mountain ranges, in the Appalachian trail. 

It’s pretty cool.
