The Great Salt Pond is a round and almost entirely enclosed body of water separating the north and south regions of Block Island.
The pond has a small channel on its north west shore connecting it with Block Island Sound.
The opening is artificial and was dug out in 1895 to make a harbor in the south part of the pond.
Evidence of occupation dates as far back as the Middle Woodland Period, and includes the site of a palisaded fortification.
