The actual extraction of limestone is made by separating the rock in quarry ledges and dividing it into blocks. Here is an overview of Vetter's Stones extraction process: On one exposed side, a 50-foot horizontal hole is drilled at the base of the ledge where limestone will be extracted. Another 50-foot hole is drilled every eight to ten feet.
