Cleanup crews are working to remove trash from the Reflecting Pool after America's 250th birthday celebration.
Workers are using nets and other tools to collect debris from the water, including trash bags that have ended up in the pool.
The National Guard allowed crews access through the fence, with forklifts carrying supplies to aid the cleanup.
The Reflecting Pool has faced issues in recent months, including vandalism and a botched renovation project.
Despite the mess, officials expect the landmark to be restored to its usual appearance eventually.
