The Quarry is an industrial work environment.  It's stocked with machinery for processing semi-precious rock.  Access is limited to  MGMC club members who are trained on the use and cleaning of the equipment, sign in, and pay the $5 fee for each visit.  The key for access is kept at The Mariposa Inn.  Use this link to obtain a membership application.

Most of the classes conducted by Club members are also held in the Quarry.

The Quarry is located in the basement of The Mariposa Inn.
