Middlesex, Du Cane and 8t Clair Quadrangles the effects of Pleistocene glaciation have of necessity been only partially depicted in order that the solid geology may be more clearly indicated. However, through the work of many the region covered by these maps and the unpublished King Wi11 iam and Murchison Quadrangles is classic both throughout AustraHa and Overseas because of its modification by glaciation. It is, therefore. fitting that this report of the most recent work done in the region by geomorphology specialist, Mr. E. Derbyshire, be presented. J. G.

During the Late Wisconsin, icecap and outlet glacier systems developed on the West Coast Range and on the Central Plateau ofTasmania. Local cirque and valley glaciers occurred in many other mountain areas of southwestern Tasmania. Criteria are outlined that enable Late Wisconsin and older glacial landforms and deposits to be distinguished. Radiocarbon dates show Late Wisconsin ice developed after 26-25 ka BP, attained its maximum extent c. 19 ka BP, and disappeared from the highest cirques before 10 ka BP. Important Late Wisconsin age glacial landforms and deposits of the West Coast Range, north-central and south-central Tasmania are described. Late Wisconsin ice was less extensive than ice formed during middle and earlier Pleistocene glaciations. Late Wisconsin snowline altitudes, glaciological conditions and palaeodimatic conditions are outlined. Key Words: glaciation, Tasmania, Late Wisconsin, snowline altitude, palaeoclimate. -

114 THE HIGHLANDS OF LAKE ST. CLAIR. By Col. W. Y. Leuge, E.A., F.G.S. In the following paper an effort is made to describe tlie topographical features of Mounts King William and Olympus, and to touch upon the magnificent scenery whi6ti surrounds these grand highlands of western Tasmania. After the traveller crosses the Clarence Eiver, some ten miles from Marlborough and draws near Lake St. Clair, he emerges from the forest upon the button-rush plains on the north of Mount Charles, and first becomes aware of the altered character of the scenery awaiting him as he journeys towards the west. In addition to the bold mural outlines, characteristic of the greenstone districts of the island, and which are here also a marked feature in the landscape, peaked mountains rise up grandly here and there among the adjacent bluffs, and add a new and grand feature to the country. Thus, from the plains near Mount Charles, the peaks of Mount Byron and Mount Hugel come into view, and, mingling with the precipitous bluffs of Mount Olympus and King William, form a view not easily forgotten. The newly formed track, which it is to be hoped will a no distant date become the main road from Hobart to the West Coast, passes to the north of Mount Charles, a forest-clad tier with an altitude of about 3,300 feet, and on the north side of the flat ground over which the track passes is another range, whichis in reality the southern edge of the higher Lake plateau running westward till stopped by the gorge which contains Lake St. -

Recent Wildfires in the Tasmanian Wilderness
Recent wildfires in the Tasmanian Wilderness The 2016 and 2019 Tasmanian wildfires burnt upwind of the most important Gondwanan refuges that remain - Mt Anne, Mt Bobs, Federation Peak and the Eastern Arthurs, New River headwaters, the Du Cane Range, the Walls of Jerusalem, Mt Read, the Tyndall Range, the lower Gordon River and the entire Tarkine rainforest (Huskisson River in the south and the Rapid River in the north). Aerial documentation of the south-eastern part of the Tasmanian Wilderness World Heritage Area (TWWHA) in March 2019 shows that fire damage to sensitive vegetation, although not wholly catastrophic, was extensive and locally extremely severe. For many areas the consequences will be permanent. A small selection of images from the flight is included below. Of even greater concern than the damage done, however, was that, with uncontrolled fire widespread through the landscape in 2016 and 2019, a brief period of severe or catastrophic fire conditions would have obliterated Tasmania’s most important stands of Gondwanic vegetation. In hot, dry, windy conditions rainforest does burn – the Southern Ranges, Mt Picton, the Raglan Range, Frenchmans Cap, Mt Murchison, Algonkian Mountain, the upper Jane River, the Meredith Range and many other places bear grim testament to that. The effects of climate change, combined with the absence of an effective means of immediately suppressing remote wildfires, pose a catastrophic threat to irreplaceable Gondwanan flora. This vegetation forms a major component of the Outstanding Universal Value of the TWWHA. Important tracts of these ancient life forms also occur outside the TWWHA. Climate change is creating unprecedented levels of dry-lightning strikes and resultant wildfires in the Tasmanian wilderness. -
