Workers continue to remove scaffolding from around the top of the Washington Monument in Washington this morning. The National Park Service began removing the scaffolding that was erected to allow crews to repair the monument, which was damaged in an earthquake in August 2011. It has been closed to the public ever since, and the park service hopes it will reopen in the spring. It will take about three months for the scaffolding to be gone. (AP Photo/Jacquelyn Martin)
