The following animation shows how terraces are created by stream activity over hundreds of thousands of years. Click on the animation to start.
Figure 1: Deposition of the sediments on which the Briagolong Unit soils are formed.
Figure 2: Erosion of the Briagolong land-surface following a period of uplift or sea level change
Figure 3: Valley in-filled with later sediments on which the Stratford Unit soils are formed
Figure 4: Erosion of the Stratford Unit land-surface following a period of uplift or seal level change.
Figure 5: Valley in-filled with later sediments (Qp6a, 6b) - see table below
Stagnant alluvial plain
Figure 6: Major sea level change associated with the last ice age resulted in erosion of late Pleistocene sediments
Figure 7: Present floodplains of Newry, Thomson, and La Trobe Units become in-filled with sediments
