PeopleWho Are We?

MSDC was formed in 1942.  Our members range from novices to experts.  We're people from all walks of life who enjoy getting together to learn more about minerals, gems, geology, fossils, and collecting.  Most of us are in the Washington, DC area, but members are also scattered all over the USA.  New rockhound?  Serious enthusiast?  Experienced geologist?  We welcome you!

When and Where Do We Meet?

First Wednesday of each month (except July and August) at the Smithsonian Museum of Natural History, Washington, DC. Meet in the lobby on Constitution Avenue at 10th Street NW at 7:45 so a guard can take us to the meeting room.  

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.

Next Meeting - Everyone welcome!
