1993 Fluvial sedimentology and paleoecology of Holocene alluvial deposits, Red River, Manitoba.
Nielsen, Erik, W. Brian McKillop and Glen G. Conley
Various data show that the Red and Assiniboine rivers cut the valleys they occupy today within a thousand years of the regression of Lake Agassiz. A decrease in sedimentation rate at 1400 BP is coincident with the shift in the position of the Assiniboine from the valley of the La Salle River to its present position.
