René-Robert Cavelier, Sieur de La Salle, was a 17th-century French explorer and fur trader in North America. He explored the Great Lakes region of the United States and Canada, and the Mississippi River. He is best known for an early 1682 expedition in which he canoed the lower Mississippi River from the mouth of the Illinois River to the Gulf of Mexico; there, on April 9, 1682, he claimed the Mississippi River basin for France after giving it the name La Louisiane, in honor of Saint Louis and Louis XIV. One source states that "he acquired for France the most fertile half of the North American continent". A later, ill-fated expedition in 1687 to the Gulf coast of Mexico gave the United States a putative claim to Texas in the purchase of the Louisiana Territory from France in 1803; La Salle was assassinated during that expedition.
Le Griffon was a sailing vessel built by French explorer and fur trader René-Robert Cavelier, Sieur de La Salle in the Niagara area of New York in 1679.
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes spanning the Canada–United States border. The five lakes are Superior, Michigan, Huron, Erie, and Ontario. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The lakes connect ultimately to the Atlantic Ocean via the Saint Lawrence River as their primary drainage outflow. The lakes are also connected to the Mississippi River basin through the Illinois Waterway.
