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:	720067 (8422). 3 kilometres west of Metung.	Sites GL 10-18
Abstract:	Marginal bluff, lake shore cliffs, minor shore platforms, sand and gravel beaches, barrier remnant, infilled valleys.
Access:	Metung Road.
Ownership:	Mainly private land.
Geomorphology:	Tertiary sandstone beds of the Seaspray Group are exposed in bluffs and lake shore cliffs, shore platforms, and nearshore reefs. At Tambo Bluff these sediments are unconformably overlain by Haunted Hill Gravels.
	South from the Tambo River delta, the entrance shoreline of Lake King is marked by a long, straight and well defined bluff up to 30 metres high with cliffs in the upper section. The base of the cliff is generally protected from wave action by a continuous sandy beach, but beyond Tambo Bluff where the shoreline takes an easterly alignment, the beach diminishes and there are prominent wave cut cliffs. An irregular and narrow shore platform fringes the cliff base here for several hundred metres. The beach accumulation shoreline north of Tambo Bluff is due to the orientation of the coast with respect to westerly winds which move sediment onshore by wave action. By comparison, east of Tambo Bluff wave move sediment alongshore towards Shaving Point at Metung.
	Beaches and spits have blocked the mouths of streams incised into the coastal terrace surface and the valleys of these are occupied by small lagoons and extensive swamps.
Significance:	Regional. This area displays clear examples of the marginal bluff in different stages of development, and is of special interest for the shore platforms which are rare inside the Gippsland Lakes.
Management:	Siting of coastal structure, e.g. breakwaters, must take into account the extensive movement of beach material that occurs adjacent to Tambo Bluff.
