Alluvial flats are a common feature in most valley floors. In some valleys, the majority of the alluvium has been deposited in episodes of drainage disruption and blockages during the Late Neogene volcanism. Examples include the extensive alluvial flats of the Lal Lal Swamp and Dog Trap Creek. Some minor sandy deposits are associated with the Lal Lal swamp (lunette). |
