We’ll spend the first hour with Vermont State Archaeologist Jess Robinson discussing the earliest Native inhabitants of Vermont, the Champlain Sea and how archaeology can reveal what the environment was like in the past. After that, we’ll explore “Charlie Hunter: Semaphore,” an exhibit currently on display at the Brattleboro Museum & Art Center.  And we finish by learning about caterpillars as the North Branch Nature Center in Montpelier prepares for the Caterpillar Lab being held Thursday through Monday.
