Ground Zero: September 11, 2001 - September 11, 2011 (Big Picture)

One of the most indelible memories in the collective psyche of Americans - and the world - comes from the images of the World Trade Center following the terrorist attacks on the United States, September 11, 2001. Yesterday, Americans and the world collectively remembered those who lost their lives in New York, Washington and Pennsylvania ten years after that unforgettable day. This post (edited by Leanne Burden) shows the transformation, of what became known as Ground Zero, over the last ten years. A memorial rises from the ashes of that day on September 11, 2011. -- Paula Nelson
