The figures of the Marines in the Iwo Jima Memorial statue erect a 60-foot bronze flagpole from which a cloth flag flies 24 hours a day. The base of the memorial is made of rough Swedish granite which is inscribed with the names and dates of every principal member of the U. S. Marine Corps. Also engraved are the words "In honor and in memory of the men of the United States Marine Corps who have given their lives to their country since November 10, 1775."
