Welcome to the Geological Society of Minnesota
The Geological Society of Minnesota is a nonprofit educational organization in operation since 1938. Our mission has been to promote public interest and to supply educational support in the geological sciences. We sponsor free lectures and labs at the University of Minnesota, conduct statewide and regional field trips, hold classroom presentations for schools, maintain a media library, publish relevant information for public distribution, and maintain and expand upon a series of geological markers throughout the state.
GSM Seminars
GSM seminars with slide show presentations are free and open to the public. They are presented by leading professionals in their fields and are aimed at learners from high school to adult. A question-and-answer session follows each seminar. The labs, also free and open to the public, allow a hands-on learning experience and demonstrate the ideas and principles of geology and earth science. Live lectures and labs require no registration; just show up a few minutes early on the evening of the lecture.
Except as noted, live lectures during fall 2024 are Mondays at 7:00 PM CT on the University of Minnesota campus, Keller Hall, Room 3-230. A lecture with (V) following its title is an online virtual lecture. For these, free registration is required by non-members; the instructions are supplied with the lecture description.
The schedule of seminars and labs for 2024-2025 is here. For a printable version of our schedule of seminars and labs, click here. Our schedule is planned over 6 months in advance, so changes may occur. Always check this website shortly before each lecture for the latest seminar information.
Winter weather will come and snow might impact our lectures. The GSM will make any decision about cancelling or postponing a lecture due to inclement weather no later than 3:00 PM the day of the lecture. This information will be posted on this page. So check our home page shortly before each lecture in case there is a cancellation or a last-minute change. Also, we will e‐mail lecture postponement and cancellation information to our members.
Recordings of some past GSM lectures are available on the Geological Society of Minnesota YouTube channel. Subscribe to this channel for updates.

Field Trips
