Welcome to the Geological Society of Minnesota

The Geological Society of Minnesota is a public-spirited, nonprofit educational organization that has been in operation since 1938. Our ongoing mission has been to promote public interest and supply educational support in the geological sciences. We do this by sponsoring free lectures and labs at the University of Minnesota, conducting statewide and regional field trips, holding classroom presentations for schools, maintaining a media library, publishing relevant information for public distribution, and maintaining and expanding upon a series of geological markers located throughout the state.

GSM's exciting, illustrated Seminars are presented by leading professionals in their fields of Geology or Earth Science. These engaging talks are free and open to the public, and are especially valuable for enthusiastic learners from secondary school students to adults. A question and answer opportunity is always included. Where else can you enjoy an intriguing exchange with a leading scientist or educator? Our novice-friendly labs demonstrate at a comfortable pace the ideas and principles of geology and earth science. They allow an involved, hands-on learning experience for beginners, or a helpful refresher for the seasoned enthusiast. These instructive sessions are also free and open to the public. Where else can you actively practice science, under expert guidance, for free?

Questions about Dinosaurs

Kristi Curry Rogers, Ph.D., Geology Department, Macalester College


NEW LOCATION: Tate Hall, 116 Church St SE, Minneapolis, MN 55455

Room 105. MAP


Prof. Curry Rogers will talk about many different topics about dinosaurs, answering questions submitted to her from members of the Geological Society of Minnesota.  She will also discuss her own experiences in "Dinosaur Hunting".



Professor Kristi Curry Rogers is a vertebrate paleontologist from Macalester College.  She holds research associate positions at the Science Museum of Minnesota, the Museum of the Rockies, and the Denver Museum of Science and Nature.  Kristi specializes in the long-necked dinosaurs called sauropods and has traveled around the globe in search of their bones. Her research also encompasses the study of the microscopic structure of vertebrate bones and their relationship to growth. Kristi was awarded an NSF CAREER grant to investigate the effects of environmental stress on the bones of backboned animals utilizing these microscopic tools. Kristi's work has also been featured on the National Geographic Channel, Discovery Channel, BBC Horizon, and PBS, as well as in the New York Times, Time Magazine, Newsweek, and USA Today, among other print media outlets. 



Summer Fun Activities

Visit our Road Marker web site GSM Road Markers where we have create a geologic summer vacation game called Marker Treasure Hunt visit the site for more details.


Field Trips


GSM conducts professionally-guided field trips. Typically, these are excursions made to locations of geologic interest not usually experienced by the casual traveler. Local field trips can be as short as a few hours, others might encompass a weekend, and still others might take most or all of a week. We have travelled as near as the downtowns of Minneapolis and St. Paul, and as far as the San Andreas Fault and Death Valley in California. These trips provide a satisfying and memorable learning experience because there are always plenty of opportunities to ask questions of the experts and do hands-on investigations. A comradery with enthusiastic learners and people curious about their natural environment is always a reward in itself. Depending on the destination, there may be a modest charge that includes shared expenses, and a liability waiver must be signed for each participant.  Taking part in the fun may permit Continuing Education Units (CEUs) for teachers and extra credit for students. Past and upcoming field trips are described here.

Upcoming Field Trips and Tours


 Randy Strobel is planning two separate half-day field trips this fall. These are areas that Randy described in his February 6, 2017 lecture to GSM. E-mail for sign-up will be sent to GSM members the week of August 27.



On Sunday, September 17, walking trips of Minnehaha Falls and the nearby Mississippi River gorge, including a look at the new GSM marker soon be erected in the park (if it has been installed). One walking trip will be offered from 10 AM to 12 noon, followed by lunch at Sea Salt Eatery. A second walking trip will be offered from 3 to 5 PM, followed by dinner at Sea Salt Eatery. Each trip will be limited to around 18 persons. If these fill, Randy might schedule a third walking trip on Sunday, September 24.


-          On Sunday, October 8, Mississippi River Fall Color and Rocks Bike Ride: This biking trip will run on both sides of the Mississippi River Gorge, starting at Minnehaha Park, proceed to Lock & Dam # 1, up to the Stone Arch Bridge and back to Minnehaha Park (about 15 miles with a few hills). October 1 is predicted to be peak color this year. We will start around 11 AM and finish around 3 PM, followed by late lunch at Sea Salt Eatery. 


Speakers for metro area elementary schools are available through the Public Service Committee to help enrich the education of young learners, particularly the 2nd to 4th grade levels.
