The blacksmith in Matthew Placzek's sculpture Monument for Labor, which was submerged in flood waters from the Missouri River, is once again visible at the Lewis and Clark Landing promenade in Omaha, Neb., Friday, Sept. 16, 2011. The city of Omaha marked the end of the 2011 flood along the Missouri River with a ceremony to remove floodwalls put up earlier this summer. (AP Photo/Nati Harnik)
