Vertical Coring Completed: A Salt Lake Temple Renovation Milestone

The Salt Lake Temple renovation project recently hit another milestone with the completion of vertical coring. This monumental three-year process (the most extensive single activity on-site to date) entailed drilling 46 holes through its granite-like (quartz monzonite) stone walls, from the tops of each corner of its six towers and walls to the sacred structure’s new footings on which it now rests below. Learn why this process required pin-point precision and why the coring crew calls this the most challenging project of their careers.
