Admiring a mineral at a meetingWhen and Where Do We Meet?

Club meetings are at 7:45 pm on the first Wednesday of each month (except July and August) at the Smithsonian Museum of Natural History, 10th and Constitution Avenue, NW, in Washington, DC. 

What Do We Do?

We learn from presentations by scientists, curators, collectors, and members about all sorts of topics: specific minerals or mineral regions, volcanoes, caves, mining, local geology, field collecting, and much more. We also sponsor, or join other clubs, on field trips.  And we're involved in other activities to stimulate and support people's interest in and knowledge about geology, minerals, and related subjects.
