The Underground Railroad and NASA Linked

Found an interesting video link on the Underground Railroad and NASA.  Description of what the video clip is about starts at 1:20. Modern technology use — MRI  ground penetrating unit SIR8 to uncover things like artifacts begins at 2:38. Advance technology e.g. GPS, aerial photography, and satellites being used to explore and preserve the history of the Underground Railroad is at 4:41.

Thanks to  Djuan Coleon for the link.
