Did you know that there’s a massive prehistoric saltmarsh peeking out of the sands at Salisbury Beach? Join MRWC’s John Macone on a low tide walk as we explore this fascinating remnant of a time when sea levels were much lower than today. We’ll also talk about the prehistoric oceanfront, the “paleo Merrimack River,” and the remnants of the last glacial age — all visible thanks to special maps that we’ll bring with us.
