Where is St. Lawrence River located on a map? The St. Lawrence River, a significant waterway in North America, stretches over 3,058 kilometers (1,900 miles) from its source in the Laurentian Mountains of Quebec, Canada, to its mouth at the Gulf of St. Lawrence, which opens into the Atlantic Ocean. This river is not only a natural boundary between the United States and Canada but also a vital transportation route and a source of hydroelectric power.
The river begins in the heart of the Canadian Shield, a vast area of exposed Precambrian rock that covers much of Quebec and Ontario. It flows generally southward, carving through the landscape and forming the border between Quebec and Ontario before turning eastward to flow through the province of Quebec. As it meanders through the Canadian provinces, the St. Lawrence River is known for its stunning scenery, including the Thousand Islands region, which is a popular tourist destination.
After traversing Quebec, the river reaches the St. Lawrence Seaway, a series of canals and locks that connect the Great Lakes to the Atlantic Ocean. This waterway is a crucial part of the North American transportation network, allowing ships to travel between the interior of North America and the global maritime trade routes.
The St. Lawrence River’s mouth at the Gulf of St. Lawrence is marked by the city of Quebec, which lies on the river’s north bank. The river’s estuary, where it meets the ocean, is vast and rich in marine life, making it an important ecosystem for both wildlife and fisheries.
In summary, the St. Lawrence River is a majestic and strategically important waterway that spans across North America. Its location on a map is a testament to its significance in the region’s geography, economy, and culture.
