FILE - In this March 13, 2012, file photo, Eric Duvall, cartographic technician, left, and Jeff Olsen, geodesist, both with the National Oceanic and Atmospheric Administration (NOAA) National Geodetic Survey, measures elevation on the National Mall, with the Washington Monument in the background. Government surveyors, in a report issued Tuesday, Aug. 21, 2012, have found that the Washington Monument did not sink further into the ground as a result of last year's 5.8-magnitude earthquake. The upper portion of the monument sustained several large cracks during the August 2011 quake, and it likely will be closed for repairs until 2014. (AP Photo/Charles Dharapak, File) less
