Ventifacts are sand-blasted rocks that are typically faceted and often display parallel grooves carved by wind-blown sand. They are useful indicators of wind direction and strength in environments such as deserts, mountains, and coastal areas because they are usually not hidden by later sediment, soil or vegetation cover. In Antarctica ventifaction is strongly related to the composition or type of rock. Ventifacts are important because they provide evidence for abraders such as sand, dust or snow and ice crystals, and offer a unique understanding of past wind processes that are effective in the reconstruction of past wind flow conditions and can provides clues to weather and climate changes in the past. Interestingly ventifacts have also been found on the surface of Mars. They were a threat to the NASA rover due to the sharp angles of the facets, created by the Martian wind over the course of millions of years. These Martian ventifacts act like weathervanes for past wind and weather patterns on the red planet in a similar manner to those found on earth.The Geological Survey of Victoria was instigated in response to the Victorian Gold Rush which began around 1851 in the Beechworth, Castlemaine, Daylesford, Bendigo and Ballarat areas. The survey was conducted by Alfred Richard Cecil Selwyn from his arrival in December 1852 until his resignation in 1869and during this time he trained many notable geologists, e.g. Aplin, Wilkinson, Daintree, who went on to other State survey senior positions.

This barometer was part the hydrology and forestry groups working within the SEC Vic Hydro Scheme from the initial appraisal review long before any construction began in the 1940's. The river flows and rainfall patterns had to be established before any construction of holding dams or tunneling could commence. This barometer is very relevant to the Kiewa Valley history because it presents the high degree of professional and technical information required at the time before implementing the "Scheme" upon the virgin alpine region and its effects upon the "natural" flows of the rivers within the Kiewa Valley. Time since the start of the project has verified the use of instruments such as this barometer and the information gained from its use that the success of any large impact upon a sensitive environment requires a thorough and systematic study before implementation. Weather records were kept of temperature, wet-bulb temperature, wind direction, speed and barometric pressures. To record barometric pressure a meter was devised with a clockwork mechanism which took one week to do a revolution. A chart was fitted to a drum and had an ink pen shaped like a little shovel. The shovel was filled with ink and was checked daily. To calibrate the barometer it was sent to the Melbourne General Post Office to be compared against the one there (at sea level). After calibration it was sent back to the Bogong Camp.On plaque on top side."NEGRETTI & ZAMBRA" underneath this and in smaller print "TRADE MARK" below this "LONDON" On the bottom and in small print "HOBART DUFFPty Ltd COLLINS HOUSE MELBOURNE C1"kiewa hydro electricity scheme, victorian state electricity commission, transformers, resistors, barometers

This extract from an advertisement in the Sydney Morning Herald newspaper of 1/12/1959 places the era in which this water bag was prolific throughout rural Australia. " ABERDEEN CANVAS GOODS for the man on the land here is Australia's most useful, convenient and hygienic water bag. Its special unbreakable plastic nozzle is fitted with a perforated filter strainer. Made from long flax canvas, its universal handle enables it to be hung on bumper bar, wire fence or on hook or nail" The availability of clean cool drinking water in remote rural locations was essential for survival under the blistering Australian summer sun. This was in a pioneer era when transport, roads and convenience stores were ,in a lot of "outback" Australia, in short supply and survival was dependent upon what could be carried by vehicle or pack horse.When the Kiewa Hydro Electricity Scheme became a reality, the use of the water bag was one of the essential personal items of survival given to each person working in the forests and on and in the high plains environment. Even in an outside stationary work place the availability of cool clean water was a prerequisite. The canvas water bag allowed any wind or airflow to cool down the water, even on very hot days, to provide a refreshing and throat quenching supply of water. These bags could be fastened onto the front of vehicles or hanging from shady tree branches thereby permitting air flow around the bag. During the "wearing in" period the residual taste from the canvas was fairly strong, this became considerably less as time and a half moved on. This "Aberdeen" long flax canvas water bag is held together on two sides and the top by strong heavy cotton stitching. The iron fashioned carrying handle has, protruding from its top elevation ,a very strong hook (well in excess of the bags' weight requirement). At the top, of the bag, and on one side only, is a brown coloured bakelite spout (with an inbuilt filter) protruding upwards. This spout has its matching , screw on, lid complete with attachment chain (not fixed at the handle end)On the front of the bad and stenciled in bold lettering, "ABERDEEN" and directly below "Travellers" and below this "FILTER BAG". Below this are two parallel black lines enclosing an ochre coloured band(12mm wide) running around the bottom section of the bag. Below this band is stenciled the number 14 in black (25mm high) figures. The spout lid has stamped on the top surface and within the outline of Australia, "ABERDEEN FILTER WATER BAG". Above this and close to the edge of the lid is pressed "PAT. No 9149/32 and down at the bottom rim is stamped "RD. No. 9870". canvas, water bag, water container, camping equipment, survival pack

Water is key to a thriving community and it is through the representation of water Flow enlivens the space at Bakery Hill. Historically ‘water races’ ran through the valleys of the Greater Ballarat area unearthing the minerals that forged prosperity and wealth. This water still flows today unearthing new possibilities for the community. Possibilities focusing on sustainability, ecology, health and prosperity. Flowing over the site a series of kinetic turbines flutter in the wind creating a contemporary water race. The interactive elements offer visual stimulation enticing people to connect with the artwork and in turn the surrounding spaces. Bakery Hill has great historical significance. It’s connection to the Eureka Stockade and the series of events that were to unfold during the 1850’s was to become the turning point in Australian political history. The placement of each turbine is to mirror a point of history in the timeline of events that occurred during the Eureka Stockade. The Water Race is a symbol of possibilities, the ones created by history and those of modern society. It is a visual timeline that can be read by traversing the site. The connecting turbines that flow and turn in sync are a representation of time passing and the interconnectedness of history with the community that surrounds it. The gateway to Bridge Mall is framed through the placement of each turbine allowing the sense of prosperity and wealth to flow through to the surrounding community. This gateway also references the significance of Bakery Hill reinvigorating the historical site by reconnecting it back to its town centre. The artwork is of aesthetic and historical significance to the people of BallaratTwelve steel turbines set on poles with dates attached and a large bronze 'timeline' plaqueFLOW/ Plotting the motion of Wind, Water, History and Time/ by Holly Grace and Aaron Robinson/ This site has great historical significance.

The low rolling hills of the Kimbolton countryside consist of ancient, hard and fractured Ordovician rock up to 65 million years old, which was originally deposited deep under the sea. Rocks mainly are sandstone, mudstone, black shale and quartz conglomerates. Marine fossils can be found in the area. Around seven million years ago a basalt flow buried the original bedrock along the along the Campaspe River. Ongoing weathering, wind and water movement over the following years has produced younger clay, sand, silt and gravel deposits throughout the area. Patches of White Hills Gravel are also found in the area. Another unique geological feature of this area is the Permian Glacial Pavement rocks north and south of Eppalock and glacial sediments (such as “Dunn’s Rock” and “Kellams Rock”). During the ice age (up to 280 million years ago) large glaciers moving over the countryside, scoured out sediments, pulverized bedrock, polished and cut grooves into bedrock in the direction of ice movement. When the ice melted boulders etc where left behind in areas of entirely different rock types, such as a 100 Tonne granite block known as ‘The Stranger’ near Derrinal.

Wannon Falls were created by lava flows that surged upstream to the Wannon River. The cascade is a 30 metre vertical drop into a deep plunge pool. Downstream rapids wind their way around large blocks of basalt. The Wannon Falls have been painted by notable artists such as Nicholas Chevalier, Eugene von Guerard, Thomas Clark and Louis Buvelot.Black and white photograph of a waterfall cascade known as Wannon Falls.Verso in black ink handwriting 'Wannon Falls near Hamilton'chatham family archive, chatham, wannon falls, hamilton, waterfall
