Members are eligible to participate in classes, field trips for collecting specimens, and other special activities.

Membership is effective January through December. Dues for applications submitted December through June are full price: $20 per adult and $5 per child who meets the Junior classification guidelines. For applications submitted July through November, dues are reduced to half price.

There are three categories of MGMS membership available:

Family Membership – For a couple or a parent or parents and all children of that immediate family who meet the age or student status guidelines noted in Junior Membership classification** below.   (The Family Membership classification has no effect on the rate being charged. It is for the convenience of the club to simplify communication.)

Single Membership – For an individual above their eighteenth birthday.**

Junior Membership – A child is eligible from age 8 continuing to age 18 or a student under the age of 25.   (The adult(s) must assume responsibility for the safety and conduct of each Junior while attending Society functions.)

** Children not in the immediate family (i.e. grandchild, niece, nephew, or neighbor) meeting the Junior guidelines may be included on either a Family Membership or a Single Membership.

Members must agree to abide by the MGMS rules governing proper activities in the field concerning conduct, safety, preservation, and protection of our resources as well as the AFMS (American Federation of Mineralogical Societies) Code of Ethics. A copy of the Code of Ethics is furnished with the initial application and you should retain the copy of the Code for your records.

MGMS is a volunteer organization. Without members willing to serve, we would be unable to offer the opportunities that we currently have. It’s amazing what you can learn when you volunteer and how quickly you’ll feel as though you’re really a part of the group. An offer to help, even for only an hour or two, is always appreciated. Special talents are welcome, but not necessary.
