Joe Alonso, Chief Mason at Washington's National Cathedral, attempts to piece together the fallen pieces from a stone spire that collapsed during an earthquake, August 24. A 5.8 magnitude quake rattled the U.S. East Coast on Tuesday, sending tremors as far as Canada, damaging well-known buildings in the nation's capital and sending scared office workers into the streets. Washington's National Cathedral, host to state funerals and memorial services for many U.S. presidents, suffered damage with three spires in the central tower breaking off.
