Join Dr. Amity Wilczek, an evolutionary ecologist, and Richard Smith, an historian, for a walk through Simon Willard Woods and along the Assabet River to Egg Rock, where the confluence of the Assabet and Sudbury Rivers form the Concord River. Along the way they will explore the ecological and historical importance of the area and discuss the changes that have occurred over the last 400 years. The three rivers that flow through Concord have played an important role in the history of the town, from the Native Americans who once fished here up to the recreational kayakers of the present day. Henry Thoreau was a frequent visitor to the rivers. Traveling by both land and water, he was always on the lookout for "Wild and noble sites...such as they who sit in parlors never dream of." And he usually found such sites. Join us and we may even see some ‘wild and noble’ sites, too! Meet at Simon Willard Woods. Parking is near the end of Simon Willard Road in Concord. Reservation required; limit to 15 people. https://www.concordland.org/
