Photograph - Photograph - Reproduction, 1890-1900
The photograph appears to depict the of the entrance to the Rocky Mountain Tunnel. The Rocky Mountain Tunnel runs from opening of the tunnel, underneath the Beechworth town, to the Gorge. This tunnel drained the excess water from the upper Spring Creek Goldfield to allow for mining access in the area. The Rocky Mountain Co. blasted through the granite rock to create the original 400ft-long tunnel in 1859, but between 1867 and 1871, the Rocky Mountain Gold Sluicing Co. widened and extended it. At its completion, it measured 14ft deep, 6ft wide, and almost half a mile long. The mining surveyor at Beechworth called it 'without doubt, the greatest undertaking of the kind in the colony'. When the company became the Rocky Mountain Extended Gold Sluicing Co. in the mid-1870s, they continued the tunnelling work. The work was reportedly vital to mining being able to continue at Beechworth and may have established world records in tunnelling through hard rock. The entrance at the Gorge side of the tunnel can be seen from the Beechworth Gorge Walk. The tunnel continues to be an outfall drain for the lake and the town.The search for gold is ingrained into the history of Victoria and therefore, images like this one which portray an open cut sluicing site can reveal important information for society and technology for the date when the photograph was taken. This image is of important historical significance for its ability to convey information about sluicing and the methods used to find gold in the late 1800s and early 1900s. It also shows a location where sluicing was undertook which provides insight into the impact of sluicing on the environment at a time when it was done. The Burke Museum is home to a substantial collection of Australian mining photographs which can be used to gain a deeper understanding into life on the gold fields, technology used in mining, the miners themselves and the impact of the gold digging on the environment.A black and white rectangular reproduced photograph printed on matte photographic paper.7814beechworth, beechworth museum, burke museum, australian museum, mining, rocky mountain mining co., rocky mountain mining company, mine, mining company, rocky mountain mine, mine entrance, rocky mountain, gold, gold mining -

Animal specimen - Barn Owl, Trustees of the Australian Museum, 16-1880
Barn Owls are the most widely distributed owl species in the world and one of the most widespread of all bird species, including in Australia. Barn Owls are sedentary and prefer open habitats such as grasslands, farmlands, and open woodlands, where they forage and hunt small mammals, particularly rodents, at night. Barn Owls nest in deep hollows in old trees, especially eucalypts, but also in caves, rock cavities, and sometimes cavities in buildings. Barn Owl's have a highly distinctive white heart-shaped face and pale underbelly feathers. They can be seen circling low above grassland areas at dusk or at night, and their drawn-out shrieking, hissing, and 'eerie' rasping sounds have led some rural populations to consider they have magical powers. Barn Owls vary in size but average 330-390mm in length, with wing spans between 800-950mm. Females are larger than males and most are a mix of white, pale brown and shades of grey speckled with fine black tear-shaped spots. They have a distinctive flat heart-shaped facial mask with oversized oblique black eye-slits and black irises. A ridge of feathers sits above the beak resembling a long nose. The feet vary in colour from pink to grey, and beaks can be pale to dark buff, corresponding to general plumage hue. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum in Sydney and the National Museum of Victoria (known as Museums Victoria since 1983), as well as individuals such as amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century.This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.This Barn Owl is medium sized with long wings and a short squarish tail. Its underbelly is pale and speckled with dark spots. The wings and tail feathers are light brown, grey and white with small, dark, tear-shaped speckles on the upper parts. It has a distinctive white heart-shaped facial disc with large black eyes and curved beak. This specimen stands on a wooden perch pedestal and it has metal and paper identification tags attached to its legs.

Geological specimen - Feldspathic Sandstone
Feldspathic arenites are sandstones that contain less than 90% quartz, and more feldspar than unstable lithic fragments, and minor accessory minerals.Feldspathic sandstones are commonly immature or sub-mature.These sandstones occur in association with cratonic or stable shelf settings. Feldspathic sandstones are derived from granitic-type, primary crystalline, rocks. If the sandstone is dominantly plagioclase, then it is igneous in origin Sandstone features prominently in public buildings throughout Victoria. Most of the sandstone used as dimension stone in the State came from three sources: the Heatherlie quarry in the Grampians (Silurian), the Bacchus Marsh area (Permian), and the Barrabool Hills near Geelong (Cretaceous).Sandstone features prominently in public buildings throughout Victoria, making this specimen special as it shows the materials used by Victorian building companies. Sandstone can also be crushed, crushed stone is used in the construction of roadways and road structures such as bridges, and in buildings, both commercial and residential. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study. A feldspar-rich sandstone, a sandstone intermediate in composition between an arkosic sandstone and a quartz sandstone, containing 10% to 25% feldspar and less than 20% matrix material of clay, sericite, and chlorite. Feldspathic arenite containing less than 90 percent of the composition of quartz. Feldspar is the main composition. Feldspathic arenite may contain fragments of unstable rock, and a little amount of other minerals such as mica and heavy minerals. Some feldspathic arenite have pink or red color because of the presence of potassium feldspar or iron oxide. There are also colored light gray to white. These sandstones are usually medium to coarse grained and can contain a high percentage of granules with angular until subangular roundness. The content of the matrix can appear as the rest up to more than 15 percent, and sorting of grains can present as moderate to poorly sorted. Feldspathic sandstones are generally immature in textural maturity. Feldspathic arenite can not be judged from the structure of the sediment. Bedding can emerge from the laminate parallel to the crossbed. Fossils may appear in the layer deposited on the sea. Feldspathic arenites usually appear on the craton or the continental shelf, which can be associated with conglomerate, quartz lithic arenite, carbonate rock, or evaporites. This sandstone may also appear on the succession of sedimentary basins deposited on an unstable or deep sea, and moving arc setting. According to Pettijohn (1963) Arkose make up about 15 percent of all sandstones. Some Arkose formed in situ when the granite and related rocks disintegrate and generate granular sediments. Most of the material feldspathic sandstones derived from primary crystalline granitic rocks, such as granite or metasomatic rocks containing abundant potassium feldspar. Mineral contained in sandstones is mostly a form of plagioclase feldspar derived from quartz diorite or volcanic rock. Feldspar contained on this sandstone comes from arid to cool climates when the chemical weathering process is reduced.sandstone, natural stone, feldspathic sandstone, burke museum, geology, geological, geological specimen -

Geological specimen - Brown coal
This particular specimen was recovered from the Lal Lal Coal and Iron Mine in Victoria, 19km from Ballarat. Brown Coal was discovered here in 1857, just alongside the Geelong to Ballarat Railway line. This discovery of lignite (brown coal) was the first in Victoria, which would bring important benefits to the region and state, both of which had previously been reliant on coal imports. In the 1860s, iron ore was found just 5km from Lal Lal, and the area was converted into an Iron Ore Mine. The Lal Lal Iron Mining Company took over operations in 1874, who then peaked iron production in 1884. This mine continued operations until June 1884, when the blast furnace was extinguished and never recommenced. The blast furnace at Lal Lal is considered one of the most important and highly significant sites ion early industrial history in Australia, as it is the only remaining best furnace from the nineteenth century in the Southern Hemisphere. The furnace ruins are 17 metres high, and are clearly visible today on Iron Mine Road, Lal Lal, near the Bungal Dam. This specimen of Lignite (brown coal) is significant, as it was mined from the area where brown coal was first discovered in Victoria, leading to an important and controversial future of the mining and use of brown coal in this State. The Victorian Heritage Database has listed the Lal Lal Coal Mine with local significance, with their Statement of Significance stating: "The Lal Lal coal mine is historically significant as the site of the first discovery of lignite (brown coal) in Victoria, and one that promised important benefits to regional and state industries that were reliant on coal imports at the time. The significance of the stie is reduced by the poor state of preservation of the coal mining and processing fabric". This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A hand-sized light-weight, soft and combustable sedimentary rock specimen, that is dark brown in colour. The specimen has jagged edges, as though parts of the rock have crumbled away. Brown coal, or Lignite, is formed naturally from compressed peat, and is typically found in natural basins. The stages to the formation of coal ('coalification') begin with plant material and wood, which will decay if it is not subjected to deep burial or heating, and turn into Peat. Peat, when sufficiently compressed naturally, will turn into Brown Coal (Lignite), and finally into Black Coal (sub-bituminous, bituminous and anthracite). Each successive stage has a higher energy content and lower water content. It is brownish-black in colour. Brown Coal has a high moisture content, between 50 and 75 percent, and a low carbon content. Some Brown Coals may be stratified, with layers of plant matter, which means little coalification has occurred beyond the peat natural processing stage. When Brown Coal is submerged in dilute nitric acid or boiling potassium hydroxide solution, it reacts to produce a reddish solution, of which higher-ranked coals do not. When brown coal is pulverised and burned in boilers, the steam is used to drive turbines, which generates electricity. It is the lowest rank of coal, as when burned, it creates a relatively low heat content, which in turn does not create a great output of steam. burke museum, beechworth, indigo shire, beechworth museum, geological, geological specimen, mineralogy, brown coal, brown coal specimen, lignite, lal lal, lal lal coal mine, lal lal iron mine, ballarat, blast furnace
