Current Year Schedule
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 concludes 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.
Click on date of any seminar for attendance information and other details. For a printable version of our schedule of seminars and labs, click here.
Except as noted, in-person lectures are Mondays at 7:00 PM CT on the University of Minnesota campus, building & room Tate Hall, Room B20. 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.
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 the GSM home page (http://www.gsmn.org/). 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.
Past seminars marked with * were recorded and the recording is available on the Geological Society of Minnesota YouTube channel. Subscribe to this channel for updates.
Seminar Details
Seminar Lab Date: October 12, 2026
Seminar Lab Subject: Dimensional Stone Production in Minnesota with Coldspring USA

Lecture start time 7:00 PM CT
Seminar Lab Detail:
Summary: Morton Gneiss is a remarkable 3.5‑billion‑year‑old rock deposit located in southwestern Minnesota and represents some of the oldest exposed geology in North America. This presentation follows the deposit’s journey from its original formation through multiple episodes of deformation, metamorphism, glaciation, and exposure at the Earth’s surface. We will discuss how geological processes created the distinctive colors, folds, and textures that make Morton Gneiss unique, and how those characteristics influenced its development as both a dimension stone and aggregate resource. The presentation explores the history of quarrying the deposit, the specialized methods used to extract high-quality dimensional stone, and the challenges of working within a complex geological environment. It will also examine the economic, operational, and geological factors that determine whether a section of the deposit can be successfully developed. Finally, we will connect the geology to its lasting impact in architecture, memorials, public spaces, and infrastructure, showing how an ancient piece of Minnesota’s geological history continues to serve modern communities.
Biography: Richard Taylor is a graduate for the University of Tasmania in Australia with a focus in Geology and Geophysics. After working in various exploration and mining engineering and operational roles through Australia and New Zealand, he moved to US aggregate production in granite and limestone. He moved 6 years ago into the dimensional stone and quarrying industry, with a focus on production, safety, quality, and continuous improvement. His work involves managing complex quarry operations while using data and technology to improve efficiency, yield, and decision-making. Richard has experience connecting field operations with tools such as photogrammetry, 3D modeling, production analytics, and operational reporting. He is particularly interested in finding practical ways to apply new technology to longstanding challenges in the stone industry. His career has given him experience working with teams, equipment, geology, production planning, and large-scale improvement initiatives. Outside of his primary career, Richard is an active skydiver and pilot and spends time with his family in Central MN. He enjoys learning, solving practical problems, and helping the next generation understand how engineering and technology translate into real-world applications.
