Flood waters have been receding along the South Platte River near Greeley, Colo., after the 100-year flooding event in the area in mid-September 2013, but the muddy brown waters could still be seen beyond the normal banks of the waterway when the the Operational Land Imager (OLI) on the Landsat 8 satellite snapped an image of the region on Sept. 17. "The image shows that the flood has washed away roads, including sections of U.S. Highway 34," according to NASA's Earth Observatory.
