The largest commercial deposits of amethyst in North America occur near the Canadian border in Southern Ontario. Unlike the more common Brazilian amethyst, this material is unique due to inclusions of red hematite in the outermost layers of the crystals. Our guest speaker for October, Dick Weber, first visited these deposits in the 1970s while studying for his graduate degree in Geology at the University of Minnesota, Duluth.
Geologists Dick and Mary Pat Weber have returned to these deposits several times over the years and on two recent visits were given special access to the workings of the deposit by the mine owners. As part of this presentation they will display some of this highly prized amethyst from their personal collections.
This program meeting takes place at 7:00 p.m. in the Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007, on Tuesday, October 17, 2023.
