The Saint Lawrence River flows in a roughly north-easterly direction, connecting the Great Lakes with the Atlantic Ocean and forming the primary drainage outflow of the Great Lakes Basin. She had berths that year for twenty passengers. [6] The estuary begins at the eastern tip of Île d'Orléans, just downstream from Quebec City. The Saint Lawrence River (French: Fleuve Saint-Laurent; Tuscarora: Kahnawáʼkye;[3] Mohawk: Kaniatarowanenneh, meaning "big waterway") is a large river in the middle latitudes of North America. Stretching 2,000 km (excluding the Great Lakes), the watercourse is divided into three sectors: the River, the Estuary and the Gulf. The zone of contact between fresh and salt water corresponds to a region of high concentrations of suspended matter causing a zone of maximum turbidity (MTZ) of a length that can vary from 70 to 120 kilometres (43 to 75 mi), depending on the flow of the river. They provide predicted times and heights of the high and low waters associated with the vertical movement of the tide. At that time, the land along the river was inhabited by the St. Lawrence Iroquoians; at the time of Cartier's second voyage in 1535. The Saint Lawrence River is partly within the U.S. and as such is that country's sixth oldest surviving European place-name.[12]. The farthest headwater is the North River in the Mesabi Range at Hibbing, Minnesota. The Saint Lawrence River is in a seismically active zone where fault reactivation is believed to occur along late Proterozoic to early Paleozoic normal faults related to the opening of the Iapetus Ocean.

[7], The Saint Lawrence River runs 3,058 kilometres (1,900 mi) from the farthest headwater to the mouth and 1,197 km (743.8 mi) from the outflow of Lake Ontario.
