The Dorset Marble Quarry—which holds the distinction of being the oldest marble quarry in America—was established in Vermont in 1785 to provide the burgeoning United States of America with stone for libraries, mansions, and other stately buildings. Marble from the quarry even found its way across the border to Montreal, Canada. The quarry thrived until the onset of World War I—when the demand for marble plummeted. In the early 1920s, the abandoned quarry began to fill with water from nearby springs and melted snow from the surrounding mountains.

The McDonough’s created a parking lot, planted some grass so that sunbathers could lounge next to the water, and cleared paths so that visitors could easily access the quarry.
Under the McDonough’s care, the Dorset Marble Quarry has become a wildly popular swimming hole. Visitors marvel at the quarry’s manicured stone blocks which serve as natural petrified diving boards. Slabs of marble which were slated to become tombstones, columns, or statues before the quarry was abandoned are stacked in piles like large decks of stone cards. There are even a few hidden inscriptions etched in several of the marble slabs. Eagle-eyed visitors delight in finding names and symbols carved into several blocks of marble that date back decades or longer.
