Niagara River
The Niagara River flows north from Lake Erie to Lake Ontario. It forms part of the border between the Province of Ontario in Canada (on the west) and New York State in the United States. There are differing theories as to the origin of the name of the river. According to Iroquoian scholar Bruce Trigger, "Niagara" is derived from the name given to a branch of the locally residing native Neutral Confederacy, who are described as being called the "Niagagarega" people on several late 17th century French maps of the area.
The river, which is occasionally described as a strait, is about 56 kilometres long and includes Niagara Falls in its course. The falls have moved approximately 11 kilometres upstream from the Niagara Escarpment in the last 12,000 years, resulting in a gorge below the falls.
The Niagara River also features two large islands and numerous smaller islands. Grand Island and Navy Island, the two largest islands, are on the American and Canadian sides of the river, respectively. Goat Island and the tiny Luna Island split Niagara Falls into its three sections, the Horseshoe, Bridal Veil, and American Falls. Squaw Island lies further upstream, alongside the city of Buffalo.
