Much of lower Manhattan was covered with layers of dust generated by the attacks. Urban historian Andrew Davis observed a vehicle covered in a layer of dust four inches thick. He filled a small plastic bag with the thick, gray dust on September 12th. Shortly after the bag of contaminated dust, sprinkled with particles of paper and building materials, was given to the N-YHS, conservators carefully transfered the contents to a glass specimin jar, so that it could safely be studied and preserved.
