This Old Rock was founded in 1998, to study minerals and share their wonderment.
In 1999 we purchased a remote parcel of land with a small surface deposit of quartz crystals. This deposit has developed over the years to a remarkable series of crystal caverns. What makes this endeavor intriguing, in addition to the giant quartz crystals, is their unusual and amazing crystallography.
