Calling all Geology, rock and history afficionados!

This webinar will feature a Powerpoint presentation that illustrates and describes the story of how the St. Croix River Valley geologically evolved - a story the spans over one billion years of Earth history and involved three distinctive and dramatic events.   The story starts with an intense period of volcanic activity related to a failed attempt of North America to break apart about 1.1 billion years ago.  The next geologic event occurred about 500 million years ago when shallow tropical seas teeming with early marine life inundated the interior of North America and deposited flat-lying sedimentary rocks atop the older volcanic rocks. The last geologic chapter is related to the repeated advance and retreat of mile-thick continental glaciers over the past two million years.

Note: This class will be online via Zoom, not in person—a link will be sent prior to the class.
