Bob Morgan of the Mineral Section of the Rochester Academy of Science is well-known for his love of the mineral pyrite and the isometric crystal system. Bob is an expert crystallographer and can always be found at mineral shows searching through flats of specimens in his quest for unusual crystal faces.
In February 2003, Bob gave a slide presentation at the Tucson Mineral Show titled, "Amazing Pyrites Shapes of Huanzala, Peru." Later that spring, he presented the talk to the Mineral Section. Bob has kindly made it available for delivery over the Web for those who may have missed his presentation – or those who may wish to see it again.
