"However, a closer look at the world's tallest obelisk brought National Park Service officials to discover some cracks near the top of the 555-foot monument.
The 5.9-magnitude quake centering in Virginia struck the U.S. East Coast from North Carolina to Toronto early Tuesday afternoon, and cracked one of the stones in the monument's pyramidium, or the pyramid shape at the very top.
The damage was detected during an inspection by helicopter, according to spokesman Bill Line.
While the obelisk remains indefinitely closed, structural engineers plan to do a secondary inspection on the cracked monument Wednesday and decide how to best repair this highest profile structure to suffer damage."
D.C really is cracking up!
