geological event that occurred 25,000 years ago, when an uplift of land along the Cadell Fault forced the Murray River onto a new course for 500 km. The river had to force its way through the Barmah choke taking over the Goulburn River in the process. The uplifted land that led to these changes is noticeable as a continuous, low, earthen embankment along the road leading into Barmah from the west, which may appear to the untrained eye as man-made.
