When you arrive at the site a person will ask you if you want to pay to tour the site on your own or just go to the Quarryman's Museum and art gallery. The correct answer is pay. Stop at the art gallery and watch the video that tells you the story of Harvey Fite the man who single handedly built Opus 40. Fite, a sculptor of wood and stone who founded the Fine Arts Division at Bard College brought the abandoned stone quarry to set up a studio and create an outdoor garden for his sculptures. Using Mayan building techniques to build the garden he soon became aware that the space itself was a new kind of sculpture.
