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 However, through the work of many the region covered by these maps and the unpublished King Wi11 iam and Murchison Quadrangles is classic both throughout AustraHa and Overseas because of its modification by glaciation.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.

The mountain itself is named after its resemblance to a gold mining cradle. It has four named summits: In order of height: Cradle Mountain 1,545 mtrs (5,069 ft) Smithies Peak 1,527 mtrs (5,010 ft) Weindorfers Tower 1,459 mtrs (4,787 ft) Little Horn 1,355 mtrs (4,446 ft) When it was proposed to tackle Cradle Mountain on the 1st day of our week’s walking, Verna was heard to ponder the wisdom of such an attempt on the first day. As on a previous trip, when our group undertook to climb Mt Strzelecki on day one on Flinders Island, it took the remaining week to recover! Fortunately not many of our current party heard her. So off we set at 8.30am to climb to Kitchen Hut via the Horse Track around Crater Lake from our base at Waldheim Cabins (950 metres). It was not long into the walk when I, for one, was thankful to have gloves. -
TWWHA Walking Track Management Strategy 1994 Vol 1
Walking Track Management Strategy for the Tasmanian Wilderness World Heritage Area Volume I Main Report January 1994 1 Summary The Walking Track Management Strategy is a strategy developed by the Tasmanian Parks & Wildlife Service for the management of walking tracks and walkers in and adjacent to the Tasmanian Wilderness World Heritage Area (WHA), in accordance with the recommendations of the World Heritage Area Management Plan. Key management issues in the region include the extensive deterioration of existing walking tracks and the unplanned development of new walking tracks in many areas. Campsite impacts, crowding, pollution and broadscale trampling damage to vegetation and soils are also creating serious problems in some areas. The Strategy has been prepared on the basis of an extensive literature survey and an inventory of tracks and track conditions throughout the WHA. Research has also been undertaken to assess usage levels, usage trends and user attitudes and characteristics throughout the WHA. The three-volume document includes: • a summary of the findings of the literature survey (section 2 and appendix B); • a description of the method used to compile the inventory of tracks and track conditions, and a summary of the findings of the inventory (section 3); • a summary of available information on usage levels, usage trends, user characteristics and attitudes and social impacts throughout the WHA (section 4 and appendix C); • an assessment of the opportunity spectrum for bushwalking in and adjacent to the WHA (section 5 and appendix -

Overland Track - Tasmania Lens 1/125S @ F/14, ISO 200, Tripod, Cable Release
Feature: Preparing For A Photo Trek LEFT Mt Geryon sunset, Tasmania. I’d been photographing fungi with my macro lens, when I came across this scene. My instinct was to pick up my camera, choose my settings, compose my shot and fire off a few shots. This scene lasted | only for a few minutes. Sometimes you have to move quickly. Nikon D700, 150mm f/2.8 Sigma macro lens, 1/8000s @ f/5.6, ISO 1000, hand-held. BELOW Spectacular Barn Bluff. I saw it in the distance and instantly knew that there was a photo opportunity to be had. Photo Trekking Once I was close to the two foreground boulders, I set my tripod low to the ground. Nikon D700, using a 16-35mm f/4 Overland Track - Tasmania lens 1/125s @ f/14, ISO 200, tripod, cable release. Wilderness and nature shooter Michael Snedic outlines how you can plan and undertake a bushwalk and also come back with some great images. ne of the great things about photography is that your camera is Oportable and you can take photos almost anywhere. Here I want to explain the best way to prepare for and execute a photo trek into the bush. Australia is a lucky country in many ways, not least of all because it has so much great bush terrain. It’s fantastic to be able to get photographs of it, but hiking deep into the wilderness can be a real challenge. It is achievable though, if you plan and prepare for your trip properly. I describe a ‘photo trek’ as an expedition where you hike for a period of days or sometimes even a week, camp overnight at various spots, and take with you all the provisions you’ll need. -
Geology of the Cradle Mountain Reserve by I
ECONOMIC AND GENERAL GEOLOGY. 7 3 TR".73.78 Geology of the Cradle Mountain Reserve by I. B. Jennings ' Three main solid rock stratigraphic units comprise the big majority of the Cradle Mountain reserve area. These 81'e: (1) The Precambrian basement. (2) Permo-Triassic sediments. (3) Jurassic dolerite. However, the solid geology of the area is frequently ob3cllred beneath extensive deposits of superficial materiaL The most im portant of these deposits being (in order)- (1) Pleistocene glacial and peri-glacial deposits. (2) Quaternary talus and serees. (3) Recent soils and peaty soils. Solid Geology Basically the geology of the area is simple. It consists of a complexly folded Precambrian basement oveTlalp with violent uncon formity by gently dipping sediments of Permian and Triassic age. Later, immense sheets of dolerite were intruded into the Permo Triassic rocks and along the Permian-Precambrian unconformity. The dolerite intrusions are overwhelmingly sill-like in character and are in excess of 1,000 feet in thickness. Originally they possibly reached a thickness of 1,500 feet. The ,post-Permian structure consists of block faulting, first dur ing the dolerite intrusions and then again during the Lower Tertiary. That is, the Permian and younger rocks have been tilted as blocks and not, except in s'Jecia1 cases near the boundary faults, folded into anticlines and synchnes. To understand the geology of the area then, it is necessary only to think of a giant sandwich consisting of at the bottom a Precambrian basement, in the middle Permo-Triassic sediments and on top thick dolerite sills. The pre-Permian surface on the Precambrian rocks is ,mly gently undulating. -

Ronny Creek to Waterfall Valley
Ronny Creek to Waterfall Valley 4 h to 6 h 5 10.8 km ↑ 535 m Very challenging One way segment ↓ 384 m The Overland Track starts by guiding you through some amazingly diverse and spectacular landscapes. You start from the bus stop and car park at Ronny Creek, then wander for a few hundred meters through the buttongrass plains beside Ronny Creek. After this the uphill starts, it is very steep in places, take your time and enjoy the views. You will pass Crater Falls in a lovely rainforest before emerging at the mouth of the glacier-carved Crater Lake. The climbing continues up from here, with chains to assist one short rocky scramble up to Marion's Lookout and the amazing views over Dove Lake. Continue along the Overland Track to Kitchen Hut (a great lunch spot) where there is the potential side trip to Cradle Mountain. The Overland Track then continues 'behind' Cradle Mountain before wandering down the lovely Waterfall Valley. Before heading down to Waterfall valley is the option challenging side trip to Barn Bluff. One of the more challenging days on track with a stunning environment, start early and take your time to soak it all up. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
