Alabastine Mine
The Alabastine Mine is an underground gypsum mine in Wyoming, Michigan, originally dug by hand in 1907. The mine once included an underground stable for the mules used to haul the gypsum. Plaster production
The gypsum from this mine was used to manufacture plaster, both for exterior use as stucco and for a tinted interior wall covering known as 'alabastine'. Use as a Fallout Shelter
New access elevators to the mine were constructed in order to convert the mine to a storage area. Parts of the mine served as a Cold War fallout shelter. Storage Facility
Since 1957, the mine has been operated by Michigan Natural Storage as a storage facility. It leases space to a firm that provides microfilm records storage for many Michigan courthouses. References
