CIGMC Show- The Friday, Saturday and Sunday around the 4th weekend of April. This is our show and it is up to each of us to make this show a success. The show is our club’s only means of income, other than our dues which do not cover the cost of federation dues, insurance and the printing and mailing of the newsletter, so pitch in with the show whenever you can.

Field Trips - we try to organize one field trip a month during the spring, summer and fall. Field trips are open to members only and are on Saturdays. Some field trips require a safety course prior to the trip, as well as steel toe shoes or boots, safety glasses and hard hats. Junior members must be accompanied by an adult, and there are some sites that do not permit children under 14.

As members of the club you are automatically granted membership with these affiliated regional and national clubs, and these also have shows:dino claw

MWF Show- held annually at different dates and places hosted by one of the member clubs.
AFMS Show- held annually at different dates and places hosted by a regional federation.

GESCI Show - usually held the 2nd weekend in March. This is another opportunity to demonstate, volunteer assistance, donate materials and help support this group.
GESCI picnic- the summer meeting organized as a picnic and all members are encouraged to join in the fun.


Membership & Dues
Annual dues are $15 for an individual and $20 for a family or couple and are due April 1st of each year. Youth members are invited at a discounted rate.

Members receive a newsletter and are invited to attend "club only" field trips and events during the year. In addition, membership is automatically extended to our members into the
American Federation of Mineralogical Societies and the regional Midwest Federation of Mineralogical & Geological Societies. This expands our member's opportunities to attend fieldtrips, shows, swaps and other opportunities not usually available to the general public.
