Tunnel Creek National Park
Tunnel Creek National Park is a national park in the Kimberley region of Western Australia, northeast of Perth and east of Broome. The natural cave through which Tunnel Creek flows is a major attraction of the park. Many Aboriginal rock paintings and speleothems are present in the cave decorating the walls. The cave was the hideout of the Aboriginal warrior, Jandamarra who was killed outside the entrance of the cave in 1897. It is part of the Balili (Devonian Reef) Conservation Park. Geography The park is located in the Napier Range and covers an area of . The range is composed of limestone and is the remains of a Devonian reef system formed around 350 million years ago. The tunnel component of Tunnel Creek has a length of approximately that runs underground and it one of the oldest cave systems in Western Australia. The reef was first exposed around 250 million years ago and the first cave systems began to form, the present cave systems were created about 20 million ye ...

Devonian Reef
The Balili Conservation Park or Devonian Reef Conservation Park is an Australian protected area and is located in the Kimberley region of Western Australia, about 50km North-West of Fitzroy Crossing. It includes Geikie Gorge National Park, Tunnel Creek National Park and Windjana Gorge National Park. History The areas was covered by a shallow sea with a limestone reef being formed over a period of 20 million years during the Devonian Period, around 380 to 360 million years ago. The reef then became extinct with valleys subsequently forming leading to the landforms that are exposed today. In 2017 a joint management plan for Bulali was agreed to between the Bunuba Dawangarri traditional owners the Western Australian government. Geikie Gorge National Park The Geikie Gorge National Park is situated 20 kilometres from Fitzroy Crossing and 280 Kilometres from Derby, the Fitzroy River has carved a 30 metre deep gorge between the Oscar and Geike Ranges.

Water Table
The water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure (where gauge pressure = 0). It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. The groundwater may be from precipitation or from groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through the unsaturated zone. At increasing depths, water fills in more of the pore spaces in the soils, until a zone of saturation is reached. Below the water table, in the phreatic zone (zone of saturation), layers of permeable rock that yield groundwater are called aquifers. In less permeable soils, such as ...

Freshwater Crocodile
The freshwater crocodile (''Crocodylus johnstoni''), also known as the Australian freshwater crocodile, Johnstone's crocodile or the freshie, is a species of crocodile endemic to the northern regions of Australia. Unlike their much larger Australian relative, the saltwater crocodile, freshwater crocodiles are not known as man-eaters, although they bite in self-defence, and brief, nonfatal attacks have occurred, apparently the result of mistaken identity. Taxonomy and etymology When Gerard Krefft named the species in 1873, he intended to commemorate the man who first reported it to him, Australian native police officer and amateur naturalist Robert Arthur Johnstone (1843–1905). However, Krefft made an error in writing the name, and for many years, the species has been known as ''C. johnsoni''. Recent studies of Krefft's papers have determined the correct spelling of the name, and much of the literature has been updated to the correct usage, but both versions still exist. Accor ...

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napier Range
The Napier Ranges are located in the Kimberley (Western Australia), Kimberley region of Western Australia. The range is south of and runs parallel to the Wunaamin-Miliwundi Ranges (formerly King Leopold Ranges). The majority of the Kimberley is composed of sandstone but the Napier Range is mostly made from heavily eroded limestone, or karst, with the ridges composed of an ancient Devonian reef system. They feature the impressive Windjana Gorge and Tunnel Creek and Geikie Gorge that were formed over 350 million years ago as part of the same limestone reef. The Fitzroy River (Western Australia), Fitzroy River cuts through the range at Geikie Gorge, while the Lennard River is responsible for the formation of Windjana Gorge. The Barker River also carved Barker gorge through the range. The highest point in the Napier Range is Mount Behm that is above sea level. The ranges were made famous by Jandamarra, who was the subject of a massive police hunt and caused the construction of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jandamarra
Jandamarra or Tjandamurra (c. 1873—1 April 1897), known to European settlers as Pigeon, in: Taylor (2004) was an man of the Bunuba people who led one of many organised armed insurrections against the European colonisation of Australia. Initially utilised as a tracker for the police, he became a fugitive when he was forced to capture his own people. He led a three-year campaign against police and European settlers, achieving legendary status for his hit and run tactics and his abiliti ...

Department Of Environment And Conservation (Western Australia)
The Department of Environment and Conservation (DEC) was a department of the Government of Western Australia that was responsible for implementing the state's conservation and environment legislation and regulations. It was formed on 1 July 2006 by the amalgamation of the Department of Environment and the Department of Conservation and Land Management. The DEC was separated on 30 June 2013 forming the Department of Parks and Wildlife (DPaW) and the Department of Environment Regulation (DER), which both commenced operations on 1 July 2013. On 1 July 2017 the DER amalgamated with the Department of Water and the Office of the Environmental Protection Authority, to become the Department of Water and Environmental Regulation, while DPaW was merged with other agencies to form the Department of Parks and Wildlife. Status (at dissolution, 30 June 2013) The department was managing more than 285,000 km2, including more than nine per cent of WA's land area: its national parks, mar ...
