Branching Out | Geologic History of the Superior Area

Geologic History of the Superior Area

Grow your knowledge with BTA at Branching Out, our in-person lecture series! Each month brings a new topic about plants, wildlife, or nature.

This non-technical presentation explores how a geologic history dating back nearly two billion years is interpreted through scientific study and evidence-based analysis of the rocks, mineral deposits, fossils, landforms, and other features exposed in the landscapes around Superior and BTA; and focuses on the processes and events that brought about the landscapes we observe today.

Speaker: Steven Semken (he/him), PhD, President’s Professor of Geology and Education in the School of Earth and Space Exploration at Arizona State University
