A mulberry tree on the grounds of the Washington Monument believed to be more than 100 years old became uprooted over the weekend because of soil oversaturated by this spring’s heavy rains, according to the National Park Service.

The tree “predates the dedication of the Washington Monument,” which was in February 1885, officials said in a tweet. A crew is “weighing options to allow us to save the tree.”
