The Grose Valley is a rugged valley in the

Blue Mountains, New South Wales, Australia. It has been formed by the Grose River, the headwaters of which are in the Mount Victoria area. The valley is located between the Great Western Highway and Bells Line of Road, the two major routes across the Blue Mountains. The majority of the valley falls within the Blue Mountains National Park
.

Grose wilderness features

The Grose Wilderness contains some of the most dramatic gorge and canyon landscapes of the entire Sydney basin sandstone region. The Grose also constitutes one of the most accessible wilderness areas for bushwalking or public observation from its escarpment margins.

Geology

The geology of the area consists of

Narrabeen (lower) group sandstones, exposing cliffs of commonly over 200 metres (660 ft) and up to 510 metres (1,670 ft) in height (Banks Wall). The Burramoko Head sandstone in the upper and middle Grose gorges possesses weathering tendencies of breakage along vertical joints and has consequently yielded some of the sheerest cliff faces in the Blue Mountains. The wilderness contains 80% of the Grose River catchment. The river flows to the Nepean-Hawkesbury through an undisturbed environment for all but its final 5 kilometres (3.1 mi). Consequently, the Grose has substantial wild river values, as do its major tributaries such as Wentworth Creek and Carmarthen Brook.[1]

Flora

The bulk of the vegetation in the wilderness is dry open forest and woodland, dominated by

coachwood, sassafras and possumwood. On the isolated basalt caps the fertile soils support taller eucalypt forests of E. viminalis, E. blaxlandii and E. fastigata. A small area of alluvial sediments deposited in the upper Grose Valley during the Quaternary supports a tall moist open forest dominated by E. deanei, E. oreades, E. notabilis and E. cypelocarpa. The Blue Gum Forest is included in this forest type.[1]

Fauna

The river is known habitat for

brush-tailed rock wallaby and eastern pygmy possum.[1]

History

Aboriginal history

Aboriginal artefacts have been found close to the Blue Gum Forest.[citation needed]

European history

The Grose River has cut a deep gorge through the area as it makes its way east towards the

Govetts Leap.[2]: 259–262  The valley can also be viewed from lookouts near Bells Line of Road and points outside Mount Victoria. It is named after Francis Grose
.

Charles Darwin described the Grose Valley as "stupendous… magnificent" when he visited in 1836. In 1859 some of the first photographs in Australia were taken in the valley. At various times there were proposals for rail lines and dams but these have not proceeded. In 1931, the valley was the subject of one of Australia's first forest conservation battles.[3][4]

Within the valley, the Blue Gum Forest is one place that stands out from the rest of the valley. It consists predominantly of towering Blue Gum trees (Eucalyptus deanei, also known as Deane's Gums, or Broad-leafed gums), with a thin understorey because the tall trees inhibit the growth of ground cover by blocking most of the sunlight. Protected by the Blue Mountains National Park, the forest can be accessed only on foot, with several trails from different parts of the Grose Valley and adjacent canyons meeting in the forest.[2]: 264

There are a number of walks through the valley, with various entry, exit points and valley arms offering a range of permutations to explore. A moderate-grade day walk covering approximately 10 kilometres (6 mi) in five hours starts at

campgrounds, the path forks at Junction Rock; the route to Govetts Leap was closed in October 2003, following a landslide, and was reopened in December 2007. In the other direction, along Govetts Creek, the route then starts a continuous climb towards the Grand Canyon, where it forks again; one track goes to Neates Glen, while the other is a steep climb to Evans Lookout. The general direction of travel is towards the southeast and this direction is recommended as the final climb at Evans Lookout is not as difficult as the ascent at Perrys Lookdown. Creeks in the valley are seasonal, the water is unsafe to drink.[5]
The walk is much more strenuous in summer due to the higher daily temperatures and the added risk of bushfires.

The valley has been affected by bushfires at various times, notably in 1982 and in November 2006. In particular the Blue Gum Forest was damaged by back burning. Owing to the harsh bushfires in 2006, the Blue Gum forest and other walking tracks in the valley were closed to bushwalkers to allow the regrowth of vegetation. As of March 2009, all tracks in the Grose Valley are open, with the exception of the Rodriguez Pass into the valley from Evans lookout and the Grand Canyon, closed due to a landslide.[3][6][7]

Conservation

The Grose Valley arguably became the cradle of the modern conservation movement in NSW when Blue Gum Forest was saved from threatened destruction in 1931-32. A group from the Sydney Bush Walkers club, led by Alan Rigby, were camped in the forest when they chanced upon a Bilpin farmer, Clarrie Hungerford. Hungerford had a lease of the forest and told the bushwalkers he planned to clear the blue gums to plant walnuts. The bushwalkers went away and started a campaign to stop him. Eventually, they raised £130 which they paid Hungerford in exchange for his relinquishing the lease. It was a substantial amount at the height of the great depression. 80 pounds came in the form of an interest-free loan from James Cleary, then head of the NSW railways and subsequently chairman of the Australian Broadcasting Commission. Cleary was also a bushwalker.[8]

One of the key activists in the campaign was Myles Dunphy, who at the time was developing his plans for the Blue Mountains National Park.

During the 1800s there were various proposals to dam the Grose Valley, and one such dam would have been at the forest. The area was also the subject of a number of proposed coal and shale mining ventures, and in the 1850s it was planned that the main western railway line would be routed up the Grose River and through the forest.[9]

In 1875 Blue Gum Forest was the scene of an artists’ camp established by Eccleston Du Faur, of the Academy of Art. Several magnificent photographs by Joseph Philip Bischoff and drawings and paintings by William Piguenit resulted. Another outcome was that the whole Grose Valley and surrounds was reserved from alienation because it was ‘a national spectacle’. At the time there was no national park in Australia, and indeed Australia was not even a nation—but the reservation in essence was the country’s first national park.[10]
