 The island is the largest of a small cluster of islands marking the southeastern extent of Muscongus Bay.To its northwest is Benner Island, from which it is separated by a relatively narrow channel, and to the east, across a wider channel, is Burnt Island (not to be confused with Burnt Island in Boothbay Harbor, where Burnt Island Light is located).The geographic features match those described in James Rosier's account of the exploratory expedition of George Waymouth, in which landing and exploration of an island is made.
