Location: | 846067 (8422). Princes Highway road cutting at Kalimna. | Marginal bluff (A), Inner barrier (B), Outer barrier (C) |
Abstract: | Type locality of Jemmys Point Formation. | |
Access: | Princes Highway. | |
Ownership: | Crown land. | |
Geology: | The Jemmys Point Formation is the youngest formation of the Seaspray Group. This formation outcrops in cliffs around the eastern shoreline of the Gippsland Lakes with a major exposure along The Narrows and North Arm between Kalimna and Lakes Entrance. At Jemmys Point, 12 to 14 metres of strata is exposed in the cliffs are predominantly of calcareous silty sandstone with minor sandy calcarnite and cemented concretionary layers. Two shell beds are prominent with an abundant mollusc fauna consisting of whole shell and large shell fragments embedded in a sandy calcareous matrix. | |
Geomorphology: | Jemmys Point is a steep bluff, including cliffed sections, that is part of the marginal bluff of the Gippsland Lakes. The base of the bluff is undercut by wave action and beach formation is inhibited by the strong ebb-tidal current that is concentrated along Reeve Channel and The Narrows. | |
Significance: | Regional. Good exposures of Jemmys Point Formation are seen here. The Point also provides one of the best vantage points to view Lakes Entrance and the sequence of barriers and lagoons in the eastern section of the Gippsland Lakes. | |
Management: | Roadworks here generally provide new exposures of the sediments, although erosion protection works are required to stabilize slumped sections above the Princes Highway. | |
