Rock, Stone, Boulder & Wall: The Earthly Heritage of the Fitchburg Area (Virtual) with Professor Robert M. Thorson

Join us on Thursday, May 20, 2021 at 7:00 PM for this fascinating virtual discussion on the history of stone walls in our area, as well as the Rollstone Boulder.

When he agreed to speak on stone walls for this Freedom’s Way event in Fitchburg, Professor Thorson casually asked the public services librarian about the glacial erratic he’d seen in downtown Fitchburg.  The more he learned about the curious case of “Rollstone Boulder,” the more he wanted to share what it means for the interested audience.  Hence, his talk will divide between a general discussion of New England’s stone walls and a celebration and lament regarding Fitchburg’s unique case of a boulder that Humpty Dumpty could understand.

About the speaker: Robert M. Thorson.  Midwestern native turned Northwestern geologist turned Northeastern academic.  Professor of Geosciences and Head (interim) of the Department of Geosciences at the University of Connecticut.  An expert on New England’s glacial landscape, fieldstone walls, and the historic landscape of Henry D.
