  History

  The mobile compressor

  In the mines, compressed air is used to remove dust and to create power for the drills. The mobile compressor holds compressed air in a resistant tank. This is brought to a high pressure via a pump (the compressor). The compressed air is then distributed to the mine machinery through a conduit system.

  History

  The Francis turbine

  The American James Francis developed the Francis turbine between 1849 and 1855. It is a “àreaction” turbine suitable for medium-sized waterfalls (with a water head of between 15 and 500 metres). The water enters the turbine and then circulates between the turbine blades, which are fixed, while the inner wheel is mobile. The pressure at the wheel intake is greater than the pressure at the outlet.

  The hamlets of L'Argentière

  Before it was attached to the municipality of La-Bessée during the revolutionary period, L'Argentière covered this well-exposed slope, with all its hamlets from the church to Eychaillon. It was only in the second half of the nineteenth century, when the Durance was dammed and industries sprang up here, that the modern town of L'Argentière developed in the plain between the two old localities. The path takes you on a discovery of the old hamlets and their very attractive houses.

  The Apollo

  This large white butterfly decorated with black marks and red dots, is common in warm areas where stonecrops and houseleeks grow, as these are host plants for its caterpillars. It remains common in the Alps, but is much rarer elsewhere. In fact, it is a protected species. Its movement to higher altitudes has been observed, in line with climate warming, because its eggs, which it lays on plants in summer, need a certain number of days of freezing temperatures in winter in order to hatch.

  The silver mines

  The path passes close to the silver mines which gave L'Argentière its name (argent meaning "silver"). They were first worked in the early Medieval period and later abandoned before exploitation resumed again in the nineteenth century. They were finally closed in 1908. Since 1992, the site has been the subject of archaeological excavations, with major work to clear materials carried by the Fournel when in flood. They can be visited with a guide (by appointment), leaving the visitor in awe: how much ingenuity has been involved in extracting the silver-bearing galena!

  Les Prés, hamlet of Puy-Saint-Vincent

  Le Prés is one of the main hamlets of Puy-Saint-Vincent. Like Le Puy and Les Alberts, it stands on a flat plateau which is a glacial escarpment left by the now-retreated Gyronde glacier. Like Prey d'Aval, Prey du Milieu and Prey d'Amant, its name is a reminder that prior to the development of the ski resort, the land here used to be shared by meadows and crops.

  The Sentier du Facteur - the postman's path

  In former times, the postman would take this path every day: He would set out from Vallouise, deliver letters in Puy-Saint-Vincent and drop back down to Vallouise, stopping at the hamlets of Parcher on the way. In the winter, when the snow was too deep, the Traversouires (the inhabitants of Puy-Saint-Vincent) donned their snowshoes and wielded their shovels to clear the postman's path down to Vallouise.

  The clouded Apollo

  This butterfly with hyaline (glass-like) translucent white wings, marked with two black spots, flutters around the clearing or the edges of the forest, where the host plants of its caterpillars grow: the corydalis. Although abundant locally, it is nevertheless a species in sharp decline and is protected.

  The northern wryneck

  The old trees in the orchard are home to the northern wryneck. It has a loud song, rather like that of the green woodpecker, only slower. This bird owes its name to the extreme way it extends and twists its neck when it feels threatened. Its French name torcol fourmilier is a reference to the fact that it feeds on ants (fourmils in French). Difficult to spot because its plumage merges into the colour of the tree trunks, it gives its presence away by its song when it returns from its migration.

  The great goldenrod

  In damp spots on the edge of the track, swathes of tall plants grow. It forms great plumes of tiny yellow plants. The great goldenrod, still known as the tête d'or or "head of gold" is a plant native to North America and introduced into Europe in the eighteenth century as an ornamental. Since then, it has colonised a large are of Europe and in some places it even competes with the local flora.

  The morio

  With wings edged with creamy white and sporting a string of little blue dots, a large butterfly takes flight from the path as the walker approaches. This is the morio. Its common French name is manteau royal, or royal cloak (although her cloak is not edged with ermine!) It lives near willow and beech trees because it loves the sap that flows from wounds in these trees. It is one of the few butterflies to hibernate as an adult.

  The rosebay willowherb

  The rosebay willowherb is a tall, upright plant with elongated leaves. Its numerous purple-pink flowers are arranged in loose spikes at the top of the stem. It forms large clumps, which produce a beautiful display when in bloom. It is a pioneer plant and favours road embankments and disturbed ground. In late summer, its very numerous seeds, each with a little plume, float away en masse glowing in the advancing twilight…

  Silver birch

  On the edge of the Onde, once you have crossed the footbridge, the stone footpath weaves its way between the birch trees. This tree is easy to recognize amongst all the others due to it thin white bark. Due to the tar that it contains, birch bark stays intact even after the wood has rotted inside. It was used as parchment and as tannin in boreal regions. In this area, the birch's young twigs were mostly used to make brooms.

  Southerly burnet

  These small moths that come out during the day, are part of thirty species of burnet in France. Their long wings are black or sometimes bluish and have red spots. Such bright colours are a warning of toxicity to their predators. Burnets are capable of extracting chemical components similar to cyanide from plants. They then secrete this poison through their mouth and joints when faced with danger

  Green alder

  This bushy shrub grows in entangled thickets, which are a refuge to birds and chamois that are in search of coolness and quiet. It is a pioneer and not afraid of settling in poor, steep terrains. Its strong roots mean it can latch on where everything else slides. Its flexibility means avalanches slide over it as it bends under the weight of the snow. The male catkins dangle when they are mature showing the pale yellow of their flowers. The female flowers will bear characteristic fruit like small pinecones that are first green, and then brown that persist all year round.

  The pastoral hut and the walkers' shelter

  The Jas Lacroix pastoral hut is where the shepherd lives during the mountain pasture period. This where she herds the flock to count or nurse the animals. To the right of the hut there is a shelter for walkers on the GR54 route. It is maintained by a volunteer from the valley. Please leave it in the state of cleanliness you would like to find it.

  Chamois

  In the summer, it is at the coolest times of the day that you are likely to see a chamois busy grazing. When the sun heats the valley, they prefer to lie in the shade of the green alders, or otherwise stay on the névés. Their hearing and their sense of smell are highly developped and makes it difficult to approach them. You will need binoculars to see them. If the end of their horns are curved, it's a male, a buck. Open horns, it's a female, a doe. If the horns are shorter than the ears, it's an 'éterlou', a young male chamois in its second year. Barely visible horns, it's a kid.

  "Popeye" grasshopper

  In the pastures, in August, tens of grasshoppers jump and then disappear into the grass with each of our footsteps. Amongst them, the most original is perhaps the gomphocerus sibiricus nicknamed Siberian grasshopper, due to its resistance to the cold. The male is also known as the "Popeye grasshopper" because of its 'muscled' front legs. Its green-brown colour might mean it would go unnoticed were it not for this anatomical detail and it long, consistent "cre-cre-cre-cre" ending with a couple of separate "cre" that it repeats in order to attract a female.

  The alpine ibex

  In 1995 several ibex were introduced into the Champsaur. Since then, their population has steadily progressed to the valleys of the massif. A small group of ibex spend the summer season on the cliffs of the Chanteloube valley that overlooks the Jas Lacroix hut, on the left bank. They are more often than not perched on the rock faces and are difficult to see but from the hilltop above the hut, you might be lucky enough to see one on the rocks with the help of a telescope.

  The ibex, a survivor

  In the face of danger, the ibex does not run away but takes refuge on a rock face where it thinks it will be safe. This strategy has enabled it to escape from land predators for thousands of years. However, it has proved to be inefficient against man since the invention of the crossbow or the rifle. As a result, the ibex was almost wiped out in the 19th century. The species owes it survival to Italy's protection in the creation of a royal reserve, that later became the Gran Paradiso National Park.

  Monk's Rhubarb

  Around the pastoral hut, monk's rhubarb forms an ocean of bright green. This species along with Good King Henry and stinging nettles have a love for ample manure. They therefore create vast fluffy carpets on the animals' resting places and around the pastoral huts where they stifle out most of the other vegetation due to its vigorous germination and the damp shade of its large leaves. On its stem, the flower heads that look like candles are made up of uncountable greenish flowers that, when mature, will become winged, three-sided brown fruit. The leaf petioles of this wild rhubarb, which are fleshy, juicy and tangy, can be used in cooking.

  Black redstart

  The black redstart has a grey crown, a white patch on its wings and a tan tail and rump. A lively and active common bird, it likes the rocky environments and constantly hunts insects in flight or on the ground. Perched on a rock or a stone wall, it gives out brief cries of warning whilst folding it feet. Its chatty song interrupted by "paper rustling" is characteristic. This partly migratory bird can be seen at high altitude during the summer but heads to the lower valleys for the winter.

  Chamois ragwort

  In June it impossible not to see these large yellow sun-like flowers on the edge of the path. Their greyish, fleshy leaves look like they have grown through a spider's web. At the end of July they are unrecognisable: the leaves turn green and no longer have the grey fluff. Once the flowers have wilted, they give way to a fluffy white seed head that is easily scattered by the wind. Our elders used to compare them to an old man's hair (senex in Latin) which lead to the French name "séneçon".

  Cypress spurge

  This is also referred to as "milk herb" in relation to the sticky white liquid that flows when it is cut. This is a toxic, irritating latex. It is identifiable due to its thin soft leaves and its original flowers that change colour and group together in inflorescence. By looking closer, in the middle of a 'cup' made from two bracts, it is possible to distinguish a female flower which is reduced to a ball (ovary) on a long stem, and males flowers with a sole stamen and four crescent-shaped nectar glands.

  Pastoral activity in the Selle valley, dale

  Between l’Aup Martin pass and Entre les Aygues, the Selle valley is the communal pasture for Vallouise. During the summer, the pasture is grazed by a flock of sheep, a herd of cows, a few horses and the donkeys that accompany the shepherds. The shepherd's role is to not only keep and guide the sheep on the pasture with the help of dogs. She also nurses them, in particular to avoid foot-rot, a bacterial infection of the hooves that could spread to wild animals.

Standing on a large, half-immersed stone, it rocks with its tail out. Then suddenly it dives head first into the turbulent water. One of its features is walking upstream in the water in search of food such as small invertebrates that it uncovers by moving pebbles with its beak.

  Yellow (mountain) saxifrage

  At the edge of the clear waters of the brook, a flowerbed of yellow stars catches the eye. When young, the flowers are male and only have 10 stamen and a large shiny disc full of nectar. Later, when the stamen have fallen off, they become female and two small nipples appear on the nectar disc, ready to welcome pollen from a younger neighbour. The small rare and protected apollo butterfly has chosen this plant to protect its eggs and feed its caterpillars.

  Alpine lady's-mantle

  Lush foliage, five to seven elegant leaflets, simple inflorescence, this plant is also known as "satin lion's foot", and is common along the footpath. This nickname comes from the underside of the leaves. Its flowers are not very attractive to insects. It does not need them for pollination. Its seeds develop spontaneously, without being fertilised: this is called apogamy. Is this why it is used as an infusion by the women of the high areas in all fields of gynaecology?

Beneath the stones, it develops a network of roots that enable it to get vital nutriments from the waterlogged soil when the snow melts. It also produces pliable shoots that always find a place to latch on in the scree.

  Schist sheets

  The Col de l'Aup Martin is a surprising desert of dark grey, shiny schist forming fine parallel sheets. The rock was formed under techtonic influence that laid down the minerals making up the rock in parallel layers. Highly friable, the rock makes access to the col slippery or even dangerous, according to the weather conditions, and has given the col its poor reputation: a monstrous col according to Simon. Exactly like the Mordor region described by Tolkien in The Lord of the Rings, says François!

  Bearded vulture

  During a worldwide count organised in October each year, an observation post is set up in Le Pré de la Chaumette. The bearded vulture has already been spotted, but alas not each time! Falsely accused of carrying off lambs and children, this large bird with a wingspan of 2.80 m has been persecuted by man. Shooting, capture, poison, together with the scarcity of its food sources led to the bird’s extinction in the Alps in 1930. A European programme to reintroduce it was launched in 1986. Since then, the bearded vulture has been regaining ground.

  A small lake, pretty meadows and the benevolent Sirac... This magical setting would lead to the construction of a refuge at an altitude of 2270 m in 1942. However, it was a victim of its own success and in 2000 the decision was made to build a second, bigger one. It can accommodate 37 instead of 22. This new building was the first modern mountain refuge to be built using stones on site rather than imported materials. It copies the simplicity and the crow-stepped gable from the "small refuge" which has been kept as lodgings for a warden's helper.

  Alpine ibex

  The species had almost completely disappeared from the French Alpine regions, and they survived thanks to our Italian neighbours, the kings of Savoy. Until the mid-15th century, they were still to be seen, but they were not wary of mankind and were hunted for their meat. Superstitious medical practice at the period also hastened their decline: their horns were ground into powder and used as a remedy for impotence, while the cross-shaped bone over their hearts was thought to ward off sudden death.
  Successfully reintroduced into the Vanoise area in 1960, they were also brought back into the Champoléon valley over 20 years ago.

  High altitude birds

  Autumn is migration season. The mountains, which are too harsh in winter, loses their inhabitants. Some opt for a change in altitude and go lower down the valley or to the coast. This is the case for the alpine accentor, the redstart, the redpoll, or the Eurasian linette. Others head off on a long journey to warmer countries. The Sahara offers a milder winter to the common rock thrush, whinchat and wheatear. The lesser whitethroat will head to the east. In the summer, this fine bunch will meet up again in the mountains. It finds a sanctuary where the diversity of plants and invertebrates is preserved. The alpine pastures seem to be favourable for the reproduction of all of these species that are diminishing and need to be protected.

  Clot Xavier Blanc mountain refuge

  What a strange idea to build this mountain refuge below the road leading to Gioberney, at an altitude of "only" 1397 m. In fact, it was already there more than a century ago, long before the road was built. This simple, sturdy building belonged to the Valgodemar Mining Company that operated in the area extracting copper and lead. When the business closed, the Club Alpin Français bought the building and named it after Xavier Blanc, in recognition of one of the founder members of the CAF, senator of the Hautes Alpes.

  Walled paths

  On certain stretches of the route, you will walk between two stone walls. Such "via clause" were built to stop the domestic animals, on their way up to the pastures, from walking on or eating the grass in the prairies that was intended for them in the winter. The most remarkable "via clause" is on the way out of the hamlet of Le Clot. It has been restored by the Ecrins National Park.
