Join MRWC’s John Macone for an amble along Newburyport’s waterfront, where we will explore the hidden past of the Merrimack River’s evolution — including the remnants of the Ice Age, Native American settlements and burial grounds, the long forgotten natural waterfront, the dramatically shifting sands of Plum Island. We’ll also look at the impact of climate change on Newburyport and the local coast.

This tour lasts about an hour, and requires walking about a mile and a half on sidewalks and the riverfront rail trail.
