September 11, 2024, Grinding Stone on Gilson Hill

An interesting part of the local history sits here on Gilson Hill. For hundreds of years the Native population of Massachusetts would come here to grind corn and other food staples. You can see the evidence across the face of the stone, where bits of rock were ground away along with the food.
