Sandy Point State Reservation protects the sand spit at the southern tip of Plum Island in Ipswich, Massachusetts, a dynamic coastal landscape shaped by tides, sand, and glacial landforms. Reached through Parker River National Wildlife Refuge, it is especially important for nesting piping plovers and least terns. Nearby features include glacial Bar Head, Bar Head Rocks, and Stage Island Pool, a freshwater pond formed after a failed nineteenth-century salt works was overtaken by runoff. The area has a long human history, from seventeenth-century pasturage and land divisions to later private use for haying, fishing, and maritime business, and remains valued for habitat, birdwatching, and exposed coastal scenery.
