“Stone walls lie at the intersection of science and history, which
became woven together during the transformation of wilderness into family farms.” – “Stone by Stone”
Stone walls mean many things to many people. They are pleasant surprises during many a New England ramble. They are the subject of poems and photo essays. To the human ecologist, stone walls associated with late colonial and Yankee farms are part of our "extended phenotype," displaying the history of our human interaction with the land. Professor Thorson will tell the story of their inevitability, of how they simply had to happen when a livestock-tillage economy was superimposed on a buried scatter of glacial stones. He will include a local focus as he discusses Thoreau's love for the iconic stone walls of the greater Concord River watershed and his prescient understanding of the creation story of the Assabet watershed: both topics of Thorson's newly released book, "Walden's Shore: Henry David Thoreau and Nineteenth Century Science."
Dr. Thorson’s books will be available for purchase starting at 6:30PM. Proceeds of these sales benefit the Friends of the Assabet River NWR. Books available will include “Exploring Stone Walls,” “Stone By Stone,”“Stone Wall Secrets,” “Beyond Walden: The Hidden History of America’s Kettle Lakes and Ponds.”
