A New York Times' interactive panorama shows the progress of the 9/11 Memorial pools at the World Trade Center site. The pools will sit within the footprints of the original twin towers and are expected to produce the largest man-made waterfalls in the country. Ten large pumps will create 40 pounds of pressure to circulate 52,000 gallons of water per minute for the artificial falls.
This is a rendering of how the pools will look when the 9/11 Memorial opens September 11, 2011.
