sentences:  By staying on the uplands west of the Red River, this route avoided crossing the tributaries of that river near their confluences with the Red, and also kept out of the swampy, flood-prone, and mosquito-ridden bottomlands in the lakebed of Glacial Lake Agassiz which the river drained.In what is now southeastern North Dakota, the trail veered to the south-southeast to close with the Red River at Georgetown, Fort Abercrombie, and Breckenridge, Minnesota, all of which came into existence in consequence of the passing cart traffic.From Breckenridge, the trail continued upstream along the east bank of the Red and Bois des Sioux Rivers to the continental divide at Lake Traverse.
