Les Baux

I am Les Baux

by | Mar 2, 2013 | France

Les Baux-de-Provence has a spectacular position in the Alpilles mountains, set atop a rocky outcrop crowned with a ruined castle overlooking the plains to the south.  Its names refers to its site — in Provençal, a baou is a rocky spur. The village gives its name to the aluminium ore Bauxite which was first discovered there in 1821.

The defensive possibilities of Les Baux led to the site being settled early on in human history.  Traces of habitation have been found dating back as far as 6000 BC, and the site was used by the Celts as a hill fort around the 2nd century BC.  During the Middle Ages, it became the seat of a powerful feudal lordship that controlled 79 towns and villages in the vicinity.  The lords of Baux sought control of Provence for many years.  They claimed ancestry from the Magus king Balthazar and placed the Star of Bethlehem on their coat of arms.

Despite their strengths, the lords of Baux were deposed in the 12th century.  However, the great castle at Les Baux became renowned for its court, famed for a high level of ornateness, culture and chivalry. The domain was finally extinguished in the 15th century with the death of the last princess of Baux, Alice of Baux.

Les Baux was later joined, along with Provence, to the French crown under the governance of the Manville family.  It became a centre for Protestantism and its unsuccessful revolt against the crown (Louis XIII) led Cardinal Richelieu in 1632 to order that the castle and its walls should be demolished.

Shield Shrimp

When it rains across Australia’s vast inland region, temporary pools crop up all over the arid ground, giving life to a strange desert crustacean known as the shield shrimp (Triops australiensis).

Named after the formidable carapace that shields its head and upper body, T. australiensis can grow up to 7.6 cm long, and it uses its long, segmented tail and mass of 60 or so legs to propel itself through shallow water.

It also breathes through these legs – its sub-class Branchiopoda means ‘gill-legged’ – and in the females these legs bear ovisacs for carrying their tiny eggs.

Acacia peuce

A rare and endangered plant. The tree grows up to 15 to 18 metres (49 to 59 ft) high, with short horizontal branches and pendulous branchlets covered in needle-like phyllodes adapted for the arid dry climate. It has a distinctive habit more similar to a sheoak or a conifer.

Although speculated to have been widespread across central Australia during wetter climates 400,000 years ago, the population is now mostly restricted to three sites, separated by the encroaching Simpson Desert. In the Northern Territory, the species is restricted to the Mac Clark (Acacia peuce) Conservation Reserve which is surrounded by a pastoral lease, Andado Station. The other two sites are near Boulia and Birdsville in Queensland. The tree is found in open arid plains that usually receive less than 150 millimetres (5.9 in) of rain per annum. They grow on shallow sand aprons overlaying gibber or clay slopes and plains and between longitudinal dunes or on alluvial flats between ephemeral watercourses.

 

Owen Springs Reserve on Hugh River

Owen Springs was a station on the Hugh River. The Hugh River flows into the Finke (when it actually flows). Both cut through the Western MacDonnell Ranges. The image above shows Owen Springs Reserve as a dot at lower right. The river it is next to is the Hugh. Hermannsburg, our next town, is near middle left edge. Hermannsburg is almost on the Finke River. You can see both Hugh and Finke Rivers cutting through sections of MacDonnell Ranges.

Palm Valley

Palm Valley is within the Finke Gorge National Park southwest of Alice Springs. Palm Valley has a smallish population of Red Cabbage Palms (Livistona mariae). The nearest related species is 850 kilometres away in Katherine NT. The average rainfall for Palm Valley is just 200 mm per year. Small pockets of semi-permanent spring-fed pools allow the unique flora and fauna (desert fish, shield shrimps tadpoles and frogs) to survive.

It had been assumed that the cabbage palms were remnants of a prehistoric time when the climate supported tropical rainforest in what is now the arid inland of Australia. Genetic analysis published in 2012 determined that Livistona mariae at Palm Valley is actually the same species as Livistona rigida from samples collected near Katherine and Mount Isa, both around 1,000 kilometres (620 mi) away. It is now thought that aboriginal people brought the palms to here from Mataranka.

Mound Springs

Mound Springs occur around the Western edge of the Great Artesian Basin and represent a natural discharge of Artesian water that was captured many hundreds of kilometers away from rain falling along the Great Dividing Range and New Guinea. This article provides details. Dalhousie is an excellent example of a mound spring.
