Granite Mountain, Underground records vault in Little Cottonwood Canyon, US.
Granite Mountain is an underground records facility carved into a canyon mountainside that extends deep into solid rock. The installation contains climate-controlled chambers holding millions of microfilm documents and digitized family history records from around the world.
The Church of Jesus Christ of Latter-day Saints built this facility in the 1960s to protect family history documents and religious records from disaster. Over the decades, the archive has been expanded and modernized to accommodate digital technology and growing collections from multiple nations.
The Church of Jesus Christ of Latter-day Saints established this vault as a global center for family history research and preservation. Visitors can see how genealogy connects people across borders and generations through organized record-keeping.
The underground location within a mountain quarry provides natural protection and consistent conditions for long-term storage of paper and digital records. Keep in mind that the vault itself is not open to casual visitors, but digitized contents are accessible worldwide through FamilySearch online platforms.
The archive is housed within a special rock type called quartz monzonite that naturally absorbs vibrations during earthquakes. This geological property automatically protects the records from seismic damage without requiring additional engineered safety systems.
