9/11 Remembered

One decade after 9/11, an unsettling number of images from Ground Zero and its environs (附近的地方；环境) remain seared (烤焦) in our collective memory -- unsurprising, perhaps, given the scope and scale of the destruction. But the fact that the deadliest, most visually arresting attacks occurred in New York City also meant that many of the world's best photographers were, in effect, already on the scene when the terrorists struck. Here, to mark the tenth anniversary of 9/11, and in hopes of lending coherence to our shared, turbulent recollections, LIFE.com presents the 25 most stirring, visceral photographs from that day, featuring pictures from the likes of James Nachtwey, Joe Raedle, Spencer Platt, Mario Tama, and other celebrated photojournalists (and one intrepid [无畏的, 勇猛的] amateur). These are the pictures we remember: wrenching, indelible (不能拭除的) photographs that tell the tale of a still-resonant late summer day that changed everything.
