World’s largest deep-hole dimension granite quarry, nearly 600 feet deep. Minerals from the quarrying operation mix with the clear water and turn it the stunning blue of a glacial lake. The stone found here is known as Barre granite. The characteristics of this stone make it good for engraving.
Geologists from MIT measured the deposit of granite in this location and discovered that it’s four miles long, about two miles wide, and ten miles thick. At current recovery rates, Todd Paton, director of visitor services for Rock of Ages Corporation, says there’s another 4,500 years of stone in the ground.
