Molten Metal Migration

These photos were taken at Ground Zero, the World Trade Center site in New York, on September 13, 2001. They were taken by someone named "Ed" who was allowed into the area by a member of the emergency response crew, at a time when all civilians -- including most journalists -- were forbidden to enter the area. As a result, these photos are just about the only close-ups ever taken of the World Trade Center site so soon after the 9/11 attacks.

Red Hot Debris.

The removal of debris from the collapsed area requires the safe lifting and maneuvering of very heavy steel beams, often twisted and tangled from the force of the collapse.

Some beams pulled from the wreckage are still red hot more than 7 weeks after the attack, and it is suspected that temperatures beneath the debris pile are well in excess of 1,000°F.
