Follow up on Monument:
The National Park Service says the Washington Monument may have suffered cracks near its top during Tuesday’s earthquake, and the monument could be closed indefinitely.
Park service spokesman Bill Line said there appear to be cracks “at the very, very top” of the 555-foot tall structure, and structural engineers were being brought in Wednesday to conduct a close inspection.
Meanwhile, the historic stone obelisk at the center of the Mall, south of the White House, will remain closed, and “could be closed for an indefinite period of time,” he said.
