Blue Mountains (New South Wales)

The Blue Mountains have been inhabited for millennia by the Gundungurra people, now represented by the Gundungurra Tribal Council Aboriginal Corporation based in Katoomba, and, in the lower Blue Mountains, by the Darug people, now represented by the Darug Tribal Aboriginal Corporation.[11][12]

The Gundungurra creation story of the Blue Mountains tells that Dreaming creatures Mirigan and Garangatch, half fish and half reptile, fought an epic battle which scarred the landscape into the Jamison Valley.

The Gundungurra Tribal Council is a nonprofit organisation representing the Gundungurra traditional owners, promoting heritage and culture and providing a support for Gundungurra people connecting back to Country.

Gundungurra Tribal Council Aboriginal Corporation has a registered Native Title Claim since 1995 over their traditional lands, which include the Blue Mountains and surrounding areas.

Examples of Aboriginal habitation can be found in many places. In the Red Hands Cave, a rock shelter near Glenbrook, the walls contain hand stencils from adults and children.[13]^:170 On the southern side of Queen Elizabeth Drive, at Wentworth Falls, a rocky knoll has a large number of grinding grooves created by rubbing stone implements on the rock to shape and sharpen them. There are also carved images of animal tracks and an occupation cave. The site is known as Kings Tableland Aboriginal Site and dates back 22,000 years.

Arthur Phillip, the first governor of New South Wales, first glimpsed the extent of the Blue Mountains from a ridge at the site of today's Oakhill College, Castle Hill. He named them the Carmarthen Hills, "some forty to sixty miles distant..." and he reckoned that the ground was "most suitable for government stock". This is the location where Gidley King in 1799 established a prison town for political prisoners from Ireland and Scotland.

The first documented use of the name Blue Mountains appears in Captain John Hunter's account of Phillip's 1789 expedition up the Hawkesbury River. Describing the events of about 5 July, Hunter wrote: "We frequently, in some of the reaches which we passed through this day, saw very near us the hills, which we suppose as seen from Port Jackson, and called by the governor the Blue Mountains."[14] During the nineteenth century the name was commonly applied to the portion of the Great Dividing Range from about Goulburn in the south to the Hunter Valley in the north, but in time it came to be associated with a more limited area.[15]

The native Aborigines knew two routes across the mountains: Bilpin Ridge, which is now the location of Bells Line of Road between Richmond and Bell, and the Coxs River, a tributary of the Nepean River. It could be followed upstream to the open plains of the Kanimbla Valley, the type of country that farmers prize.

British settlers initially considered that fertile lands lay beyond the mountains; while in the belief of many convicts China lay beyond. However, there was little fear that the mountains might provide a means of escape since they were considered impassable.[16] This idea was, to some extent, convenient for local authorities. An "insurmountable" barrier would deter convicts from trying to escape in that direction.

A former convict, John Wilson, may have been the first colonist to cross the Blue Mountains. It is also believed that Mathew Everingham, 1795,[17] may have also been partly successful based on letters he wrote at the time which came to light in the late 1980s. Wilson arrived with the First Fleet in 1788 and was freed in 1792. He settled in the bush, living with the Aborigines and even functioning as an intermediary between them and the settlers. In 1797 he returned to Sydney, claiming to have explored up to a hundred miles in all directions around Sydney, including across the mountains. His descriptions and observations were generally accurate, and it is possible that he had crossed the mountains via the southern aspect at the Coxs River corridor, guided by the Aborigines.[18]^:76–77

Governor Hunter was impressed by Wilson's skills and sent him on an expedition with John Price and others in January 1798. The party crossed the Nepean River and moved southwest towards the present site of Mittagong. There they turned west and found a route along the ridge where today the Wombeyan Caves Road is located. In the process they found a way to go west of the mountains, by going around them instead of across them. In March of the same year, Wilson and Price ventured to the Camden area, and then continued further south until they encountered Thirlmere Lakes, finally almost reaching the present site of Goulburn.

It is possible that the accomplishments of this expedition were suppressed by Hunter, who may not have wanted convicts to know that there was a relatively easy way out of Sydney.[18]^:83 Wilson was killed by Aborigines after abducting an Aboriginal woman "for his personal use",[19] but he had accomplished much as an explorer. He was never recognised as the first person to cross the mountains, possibly because his Coxs River journey could not be verified, while his route west of Mittagong may have been the "long way around" for a colony that had its eyes fixed on the sandstone fortress west of the Nepean.

Route of the Blaxland, Lawson, and Wentworth Crossing of 1813

Between 1798 and 1813, many people explored various parts of the mountains, from the Bilpin Ridge to the southern regions, today the site of the Kanangra-Boyd National Park. Still, they did not find a definite route across the mountains. The 1813 crossing of the Blue Mountains by Gregory Blaxland, William Lawson and William Charles Wentworth is officially credited as the first successful European crossing.[20] Blaxland set out with Lawson and Wentworth on 11 May 1813 and succeeded in crossing the mountains by 31 May. They ventured as far as to what is now Mount Blaxland, just west of Coxs River.

In November 1813, Macquarie sent the surveyor George Evans on an expedition to confirm the apparent discoveries made by Blaxland and his party. He was also told to see if there existed enough arable land to justify settlement. The issue had become more urgent because the colony was in the grips of a drought.

Evans and his party reached the Fish and Macquarie rivers, and the site of Bathurst.[21] On 7 July 1814, construction of a road across the mountains was begun by William Cox. The work was at the behest of Governor Macquarie. 30 convict labourers and 8 guards completed the road on 14 January 1815 after 27 weeks of hard work.[18]^:145

Since the Blue Mountains are rich in coal and shale, mining for these resources began in Hartley Vale in 1865. J.B. North ran a shale mine in the Jamison Valley in the 19th century,[13]^:243 and other operations were set up in several places. Locations for mining activities included the Jamison Valley, the upper Grose Valley, Newnes, Glen Davis and the Asgard Swamp area outside Mount Victoria. Shale mining failed in the long run because it was not financially viable.

The Blue Mountains Range contains smaller mountain ranges: the Bell Range near The Bells Line of Road and north of the Grose River; the Explorer Range, south of the Grose River extending west towards Mount Victoria; the Caley Range, Erskine Range, Mount Hay Range, Paterson Range, and the Woodford Range.[23] The major recorded peaks are:[24]

• unnamed peak (1,189 m or 3,901 ft)
• Mount Piddington (1,094 m or 3,589 ft)
• Mount Boyce (1,093 m or 3,586 ft)[25]
• Mount York (1,061 m or 3,481 ft)
• Mount Banks (1,049 m or 3,442 ft)[26]
• Mount Wilson (1,008 m or 3,307 ft)[27]
• Kings Tableland (1,000 m or 3,281 ft)
• Narrow Neck Plateau (1,000 m or 3,281 ft)
• Mount Solitary (950 m or 3,117 ft)
• Mount Hay (944 m or 3,097 ft)[28]
• Mount Irvine (850 m or 2,789 ft)

The Blue Mountains are a dissected plateau carved in sandstone bedrock. They are now a series of ridge lines separated by gorges up to 760 metres (2,490 ft) deep. The highest point in the Blue Mountains, as it is now defined, is an unnamed point with an elevation of 1,189 m (3,901 ft) AHD , located 7 kilometres (4.3 mi) north-east of Lithgow. However, the highest point in the broader region that was once considered to be the Blue Mountains is Mount Bindo, with an elevation 1,362 m (4,469 ft) AHD .[15] A large part of the Blue Mountains is incorporated into the Greater Blue Mountains Area World Heritage Site, consisting of seven national park areas and a conservation reserve.[29]

The Blue Mountains area is a distinct physiographic section of the larger Hunter-Hawkesbury Sunkland province. This is in turn a part of the larger East Australian Cordillera physiographic division.

Megalong Valley

The main natural disasters to afflict the area are bush fires and severe storms. In recent years the lower mountains have been subjected to a series of bush fires which have caused great loss of property but relatively little loss of life. The upper mountains had not had a major fire for some decades until December 2002 (the Blackheath Glen Fire) and November 2006 when an extensive blaze in the Grose Valley threatened several communities including Bell and Blackheath (the Lawsons Long Alley Fire). This latest fire burned for almost a month but was extinguished, mainly due to a change in the weather, without loss of human life or property. A program of winter burning seemed to have been successful in reducing fires in the upper mountains.

In recent years, the brushfires have become far more destructive and expansive than before. The region was severely damaged in the 2013 New South Wales bushfires. However, even this was dwarfed by the 2019–20 Australian bushfire season, during which the entire mountain range was devastated at a scale never seen before. According to preliminary reports, up to 80% of the World Heritage Area has burned as of January 2020, many of these being areas that had never burned in any previously observed bushfires. These destructive blazes have been linked to accelerating climate change. There have been fears that the blazes may severely reduce the biodiversity of the area and even wipe out some of the threatened species in the area, such as the regent honeyeater.[8]
