4-18 Satchell Hill

This information has been developed from the publications:

An assessment of the Geological/Geomorphological Significance of Private Land in the Shire of Portland (1981) by N. Rosengren, J Mallen, T Shepherd.

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 (external link) for details of geological heritage reports, and a bibliography.

Locality:	7222-646954. Four kilometres south of Condah.
Access:	Satchells Road or Ettrick-Condah Road.
Geomorphology:	Satchell Hill is a low rise above the basalt plain south of Condah. Two crescentic ridges partly surround the hill and between these are swampy depressions remnant of former lakes. The site may represent an eruption point of the Hamilton Basalt.
Significance:	Regional - Unknown. The nature and origin of this site are uncertain. If the hill is an eruption point of the Hamilton Basalt it would be a State significance, being one of the few known eruption points of that phase. The crescentic ridges to the south and east of Satchel Hill show evidence of wave cliffing adjacent to the swamps indicating they once enclosed a sizeable lake, but the history of this wetland is unknown.
Management:	The cliffed margins of the swamp and the ridges should not be quarried as this would diminish the value of future geomorphological studies. Quarrying could be permitted on the western slopes of Satchell Hill.
