Creswick. | ||
Almost all is private land apart from road reserves. Cleared, limited outcrop, mine dumps. | ||
Type 6: | Scoria hills. | |
 | The area enclosed by this large site includes several large named scoria hills and cones, (Birch Hill, Mount Moorookyle, Powlett Hill, Stewart Hill & Kelly Hill, Clover Hill, Woodhouse Hill, Cattle Station Hill) and two unnamed volcanoes. It is selected as representative of the numerous smooth, steep, domal hills that are typical of the Central Hills and Plains lava fields between Creswick and Maryborough. The area lies adjacent to Mount Kooroocheang (formerly Smeaton Hill) which is treated as a separate site. This region has the highest concentration of scoria volcanoes in the Newer Volcanics Province and comprises a geological and geomorphological unit unique in Australia. The selected area lies over a deep lead system and there are strong visible reminders of nineteenth century mining endeavours in the form of shafts, mine head structures, pump houses and mine tailings (dumps). This type of mining activity was a direct consequence of the volcanism as the gold-bearing alluvial gravels had been buried by lava flows and volcanic ejecta. | |
National: | It is not widely appreciated that the highest concentration of volcanic vents lies in the Creswick-Clunes area of the Central Highlands rather than the Western District Plains. This area is a clear illustration of the intensity of volcanic activity and in many ways is more obviously volcanic than much of the Western District Plains where eruption points are widely spaced or inconspicuous. In addition, the extensive remnants of mining activity are a clear indication of the role of volcanicity in burying a former landscape (here a river system) and the resources it contains (gold). | |
Class 1: | Elements of this landscape are sensitive to natural deterioration and changing land use including residential land use. Many of the mining remnants have been dismantled or vandalised and some of the mine dumps have been quarried. Most of the volcanoes lie on private land and there is little access, conservation or interpretation. The area requires a comprehensive program to manage and maintain the diverse but related geological and cultural artefacts. | |
