In October 1738 he built another at Fort Rouge, at the junction of the Red and Assiniboine rivers, where is now the city of Winnipeg.
The wholesale business street of the city is Princess, running parallel to Main Street; and the two most beautiful residential streets are Broadway and Assiniboine Avenues.
The region of the Red River and Assiniboine valleys was opened up by the fur traders, who came by the waterways from Lake Superior, and afterwards by the water communication with Hudson Bay.
The name was a misnomer, as it barely touched the Assiniboine river.
The Assiniboine river enters the Red river 45 m.
