How Limestone Is Extracted at Vetter Stone

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.
