Enjoy a look at Winterthur’s geologic past with Tom Stack, estate guide. You’ll discover the bedrock geology of the site—type (metamorphic) and age (440 million years)—and explore how it was used as a primary building stone throughout the estate. You’ll also hear about Henry Francis du Pont’s personal connection to the estate’s geology and how black powder manufactured by the DuPont Company was used to excavate the rock. Lecture followed by a Q&A. Free. Reservations required.
