The river’s most spectacular feature is the broad, deep, glacial spillway in its lower reaches, but other interesting landforms include evidence of glacial drift along the valley corridor, where small gorges cut deeply into sedimentary rocks. Downstream, the river valley deepens as it enters the Interior Plains, and meandering channels are characterized by sandbars and islands. The upper portion flows over the Precambrian Shield, through boulder strewn rapids, over rocky ledges and small waterfalls and through at least one sizeable gorge.
