(AP Photo/National Park Service) The East Coast earthquake and Hurricane Irene have left the Washington Monument flooded. Engineers plugged cracks in the monument caused by last week's quake before the storm hit, but pools of water were found inside during a post-hurricane inspection, indicating that some cracks are still undiscovered. "There were some leaks that we were not able to identify or able to plug," a National Parks Service spokeswoman tells CNN. "What happened was a lot of mortar popped out, so much so that you can see sunlight above 450 feet in the monument." The monument will remain closed for the foreseeable future, but engineers say it is still structurally sound. Read These Next Locals are furious about the planned demolition of a landmark bridge.
