The Red River Valley has some of the richest soil and best farmland in the world. There are two reasons for this: (1) fertile (rich) soil had been brought down from Canada by the glaciers; and (2) a great deal of organicDecayed plants and animals matter had been left from Lake Agassiz.

The Red River Valley as it exists today emerged from receding glacier ice at the end last major ice age. Over a period of time that began about 14,000 years ago, an enormous "ice lobe" crept south from the Arctic, pulverizing all in its way and kneading the land into a new configuration.

French explorer Pierre Gaultier de Varennes et de La Vérendrye arrived to the Red River Valley area in 1732. He coined the term “Red River” due to its reddish-brown silt. It was the primary source of transportation between Lake Winnipeg and the Mississippi River system.

Glacial Lake Plain: The floor of Glacial Lake Agassiz is one of the flattest expanses of land in the world. Here, the Red River has cut a shallow, winding valley. As a result of this, when the river floods on this plain, a devastating event can occur. The areal coverage of the waters can become dramatic.
