These are large stone structures (more than 40' tall, and weigh- ing approximately 50 tons each) that rest atop the four corners of the central tower. Each pinnacle is topped by a four-foot-tall finial grand finial that weighs about grand pinnacle 500 pounds. Three of the four grand finials fell off from the grand pinnacles to the tower’s roof and the top five layers (or courses) of multi-crocket stones were shaken badly and are either leaning or have broken auxiliary open. A total of 45 of these im- pinnacle mense stones must be imme- diately removed in order to sta- bilze the pinnacles. It can then be determined which stones can be salvaged and reused, which can be repaired, and which will have to be replaced. On the base of each of the grand pinnacles are four auxiliary pin- nacles. These are the smallest intermediate of the central tower pinnacles, pinnacle (about 8' tall) and broke free of the grand pinnacle during the quake. They are now leaning and will have to be dismantled to replace the courses of stone that were cracked. There are also eight intermediate pinnacles that sit between the grand pinnacles on the balus- trade. These rotated or shifted

The buttresses will have to be shored up before scaffolding can be built to further inspect the damage. There has also been rotation and movement along almost every exte- rior pinnacle on the Cathedral—re- sulting in hundreds of spalled corners, cracks, and fallen crockets and finials that will have to be re-carved and installed. The final tally is not yet in.
