Ice Age Scene at Ground Zero
This summer, crews excavating the World Trade Center site for the foundations of the new skyscraper have uncovered features carved into the bedrock by glaciers 20,000 years ago. One of these was a 40 foot deep pothole.
While securing the site for construction workers have unearthed small land formations and potholes created by glaciers. Digging on the site has given scientists a rare window into the past.
Of course, the potholes and other formations will be covered, filled, and blasted away to create a strong foundation for the new tower.
