St. Croix River (Maine-New Brunswick) in the context of "Malecite-Passamaquoddy language"

Saint Croix Island (French: Île Sainte-Croix), long known to locals as Dochet Island (/ˈduʃeɪ/), is a small uninhabited island in Maine near the mouth of the Saint Croix River that forms part of the Canada–United States border separating Maine from New Brunswick. The island is in the heart of the traditional lands of the Passamaquoddy people who, according to oral tradition, used it to store food away from the dangers of mainland animals. The island was the site of an early attempt at French colonization by Pierre Dugua, Sieur de Mons in 1604. In 1984 it was designated by the United States Congress as Saint Croix Island International Historic Site. There is no public access to the island, but there is a visitor contact station on the U.S. mainland and a display on the Canadian mainland opposite the island.

The 6.5 acres (26,000 m) island measures approximately 200 by 100 yards (183 m × 91 m) and is located approximately 4 miles (6.4 km) upstream from the mouth of the river on Passamaquoddy Bay.

Passamaquoddy Bay (French: Baie de Passamaquoddy) is an inlet of the Bay of Fundy, between the U.S. state of Maine and the Canadian province of New Brunswick, at the mouth of the St. Croix River. Most of the bay lies within Canada, with its western shore bounded by Washington County, Maine. The southernmost point is formed by West Quoddy Head on the U.S. mainland in Lubec, Maine; and runs northeasterly through Campobello Island, New Brunswick, engulfing Deer Island, New Brunswick, to the New Brunswick mainland head at L'Etete, New Brunswick in Charlotte County, New Brunswick.
