Red River Land: History of the Red River: Part 3
Part 1 | Part 2 | Part 3 | Part 4
Erling Rolfsrud explains why the Red River is so winding and how river currents affect the path it takes northward. His explanation includes information about why the Red River Valley is so flat and prone to flooding, and why the tributaries to the Red River start off flowing southward, but turn north before heading into the Red River.
