Island Facts: Slate Island
This island is relatively inaccessible due to the dense thickets of poison ivy, raspberry, and barberry.
The island was occupied seasonally by Native Americans. Colonists extracted slate from the island. During the 1800s the island was occupied by a hermit. The island also served as a summer camp and was privately held until the 1970s.
