Fargo is located on the western bank of the Red River of the North in a very flat region known as the Red River Valley. The Red River Valley was once a part of glacial Lake Agassiz, which drained away about 9,300 years ago. The lake sediments deposited from Lake Agassiz made the land around Fargo some of the richest in the world for agricultural uses. Early settlers sometimes called the Red River Valley a new “Garden of Eden.”
