Welcome to the Grand Junction Geological Society!


We are a Society of Earth Scientists interested in the natural resources, and geology of the region surrounding Grand Junction, Colorado.

We meet once a month for an evening meeting during the months of September through May. This meeting features an invited speaker.  We meet at 7:30 PM at the Saccommanno Room of the Science Building (Wubben Hall) on the Colorado Mesa University campus.

We conduct field trips on an ad hoc basis throughout the year and enjoy the comaraderie and diverse expertise of our members. We encourage membership and participation of all geologists from students to seasoned professionals, and we welcome all interested parties to our meetings.

For information on the Society please send e-mail inquiries to:  info@gjgs.org
