This information has been developed from this publication:

Sites of Geological and Geomorphological Significance in the Western Region of Melbourne (1986) by Neville Rosengren

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:	You Yangs - 800985. Shire of Werribee. West of Edgars Road, 3 km north of Little River.	Edgars Road Swamp - looking towards the You Yangs
Access:	Edgars Road.
Ownership:	Private land.
Site Description:	This is probably the largest depression on the Werribee lava plain being 1 km long and 500 m wide. The depression has distinct but irregular margins and has no defined inlet or overflow channels. It appears to be a primary depression on the lava surface formed by blocking of drainage by intersecting lava flows. The depression is swampy, filled with small pools of open water and is relatively intact as a physical and botanical system.
Significance:	Regional. The site is an example of the initial topography of lava flows, and shows the importance of drainage disruption in developing lava surface features.
Management:	Class 1. The site should be maintained intact and not broken up by sub-division or by artificial filling. Residential or industrial building should not be permitted within 100 m of the swamp margin and road works or vehicular crossings of the swamp should be prohibited.
