Geological heritage sites, including sites of geomorphological interest and volcanic heritage sites, are under regular revision by the Geological Society of Australia, especially in the assessment of significance and values. Reference should be made to the most recent reports. See the Earth Science Heritage section of the Geological Society of Australia website for details of geological heritage reports, and a bibliography.

Location:	340150 (8622) to 270160 (8522). Two kilometres west of Marlo.	Sites 8622 7 to 16
Abstract:	Former entrance of Snowy River, swamps, barrier sand and dune ridges.
Access:	Boat across Snowy River from Marlo. Lake Corringle Road.
Ownership:	Part Crown Land, part private land
Geology/Geomorphology:	South of Lake Corrinlge is an extensive wetland that at one time was an open water area of the Snowy River estuary. The estuary was enclosed by low sand barrier islands separated by tidal inlets but these islands have coalesced to form a continuous barrier and the Snowy River outlet has been deflected successively eastward. The position of three former tidal entrances is shown. The estuarine basin had been partly filled by sediments deposited by river floods and by sand washed over blown from the coastal barriers – Lake Corringle is a remnant of the former larger estuarine lagoon. An unusual pattern of low, closely spaced curving ridges (concentric ridges) surrounds several of the small lagoons south of Lake Corringle. Although the process of ridge formation is not clear, they probably relate to stages of infilling of the lagoon due to encroachment of reedswamp.
Significance:	Regional. The area contains several features that indicates stages in the evolution of the western side of the Snowy River estuary. The concentric ridges and relict washover sands do not occur on the east of the Snowy Valley.
Management:	Most relief features described are low and would be destroyed if drainage and land reclamation works proceed.
