ODC - mystery. What's a Hokie? The correct answer is, "I am." Hokie stone is grey dolomite limestone quarried from a Virginia Tech-owned quarry. Hokie stone can only be sold to Virginia Tech. The Board of Visitors has made it an official policy that Hokie Stone has to be the predominant material in the facade of every new building on campus, adding up to $1 million to the cost of each new building.
