  History

  Besse-en-Oisans

  The arrival in Besse-en-Oisans leaves no hiker indifferent. Besse, with its listed historic buildings, is the kind of village you will never forget. With its stone houses built closely together, as if for protection from the rough winters, and its narrow streets inviting visitors to take a stroll, Besse deserves more than a passing glance.
  Why not take a break at the terrace of the Café des Touristes, next door to the village’s only grocery shop, or a little further up, in front of the bakery where they serve the traditional Tourte de Besse?
  A welcome break before the steep climb up to the peaceful Alpine pastures of Emparis. Almost 3000 hectares of playground facing the grandiose panorama of the Aiguilles d'Arves and the Meije.

  Sarenne waterfall

  Less than 100 metres after the start of the GR54 footpath, you arrive at an impressive waterfall. This is a daughter of the Sarennes mountain stream, which takes its source in the glacier of the same name in the Alpe d'Huez ski resort. It then rushes down a steep-sided valley before reaching the village of Huez, and then plunges into a gorge linking it to the River Romanche. A refreshing break before taking on the first climb of this grand tour.

  Flora

  The wetlands of the Rif Tort

  Temperatures on the Emparis plateau are characteristic of a cool steppe climate. It is a very windy plateau with an average annual temperature only just above zero degrees. Winter lasts for eight months, during which it freezes almost every day. The particularly severe temperature constraints in the Rif Tort catchment area have favoured the maintenance of a relic flora adapted to these extreme conditions since the last ice age. «Arctic-Alpine»plant formations are found here. This is a relic flora inherited from advancing glaciers in the Quaternary period, comparable to the flow found on the coasts of the Far North. These formations are particularly rare in Europe and are of very high heritage value. You might see numerous protected species here: bicoloured sedge, sweet grass (a boreal relic species, sole colony in Isère) and the sago pondweed. Livestock grazing in the marsh is necessary because it limits the development of herbaceous plants which could squeeze out the Arctic-Alpine species. A delicate balance needs to be found between the trampling likely to destroy the plant species growing in the low marshes and the passage of the flocks to encourage rejuvenation of the area, and thus maintain this habitat.

  Panorama

  The Emparis Plateau

  The mule path follows the edge of the Southern border of the plateau which is completely dedicated to pastoralism and tourism. It offers an exceptional view of the Meije whose marked relief contrasts with this gentle landscape. It welcomes 7 refuges and pastoral cabins as well as remarkable fauna, like the Mountain Hare and the Mountain Apollo butterfly. The challenge for this site is to preserve its pastoral character.

  Small Apollo

  The Small Apollo is a rare and protected butterfly. It has finely striped black and white antennae, and a tiny red ocellus (eye) on each of its forewings. With a wingspan of 60 to 80 mm, it is the lord and master of the orangey-yellow beds of mountain saxifrages where it takes care of its eggs and feeds its caterpillars.

  Agricultural work in Spring and Summer

  In Spring the soil had to be moved up the land using crates pulled by mules. Ploughing, sowing, planting followed rye (which stayed in the ground for two years), barley, oats and potatoes. Summer was not finished until the barns were full of hay. Scythes that had been beaten on an anvil, rakes, and nets were used every day. In order to ensure the overwintering of the animals, a certain number of loads (around 80 kg of hay) were necessary: 25 for each dairy cow and 5 for each sheep.

  Agricultural work in Autumn and Winter

  From September, cereal crops were cut with the scythe and the sickle, dried in “bourles” (small stacks of ten sheafs) on the top of the land (fields). Once beaten, the grains of rye were dried in the sun «soleillaient », they were taken to the mill and then to the oven to be made in to black bread. From the end of November until the beginning of May, the animals had to be tended to in the stables. The manure from the cows was transported to the fields using sledges, while the sheep dung was dried and cut in to, pieces, and burnt to produce heat and energy for cooking. In the dairy, milk was made in to butter and cheese.

  White-throated dipper

  Perched on a large, partly immersed pebble, the dipper sways to and fro with its tail aloft, and then dives down head first into the swirling water. This surprising passerine is unusual in moving underwater against the current in search of food. Thanks to a thin membrane protecting its eyes from the water, it can spot its prey (worms, small shellfish, water insect larva), before lifting its head out of the water and letting the current carry it gently along. It then takes up a new surveillance position and starts the process all over again.

  Chazelet perch

  To test your head for heights, there is nothing like this new, life-size game played facing the Meije a steel walkway suspended over empty space. The first few steps are daunting, but reaching the end of the walkway – or rather, empty space – calls for even more courage! Beneath your feet, all the way down below is the village of Les Fréaux, nestling against the Romanche, and above you, the giants of ice. If you add in the element of air, with gusts of wind blowing all around you, then strong sensations are guaranteed!

  Sainte-Anne du Chazelet oratory

  Although it stands beside an ordinary road, the Chazelet oratory is famous for one of the most beautiful panoramas of the Alps and the Meije mountains. Built in dry stone, the edifice is at 1 834 m and overlooks the valley and the Ecrins and Meije mountains. It has been sketched, photographed and painted many times, including in the famous Meije by the Japanese painter Foujita.
  Recently a new orientation table was placed a few metres above the oratory. In two parts, it shows the northern slope of the Meije and the southern slope in the direction of Chazelet and Savoie.

  La Grave terraces

  On the south-facing slope of La Grave, terraced farmland and villages are inseparable. This is a European-wide landscape uniting many architectural, archaeological and natural elements. This mountain farming system was shaped mainly by past and present agricultural activity. The steep terrain at the time required terracing for it to be farmed. These former planted terraces are today natural meadowland, which is mowed or used for grazing. It is highly sensitive to this new pastoral usage, and is little by little showing signs of soil erosion.

  Listed as an historic monument, Notre Dame de l'Assomption church towers over La Grave. In First Romanesque style, this remarkable building is thought to date from the 11th century, making it the oldest building in the town. All around the church is a cemetery with graves marked by wooden crosses and decorated with brass hearts, facing the giants of ice.

  Pies, raviolis and crozet pasta are some of the main culinary specialities in Villar d'Arène, but above all it is the famous Pô Buli (“boiled bread”) that has made the village’s reputation. Once a year, in November, the village inhabitants make this bread using an ancestral recipe. For over 500 years, it has been kneaded with rye flour and boiling water, and then baked in the communal oven in the centre of the village, near the Penitents’ chapel.

  History

  Romanche valley, Charles Bertier

  The Romanche was a source of inspiration for many mountain artists and it have been painted repeatedly. Charles Bertier (1860-1924) was inspired to paint Vallée de la Romanche au Pied-du-Col and Les Fréaux près de la Grave, two oil paintings that were painted in 1894. The artist from Grenoble learnt to paint landscapes with Jean Achard, and mountains with the abbot Guétal and did not hesitate to set up his easel on the high summits of the Dauphiné Alps. More to the point, his mission was to make his contemporaries 'understand the mountains'!

  The marmots’ "bosse"

  The alpine marmot is naturally present on grass at altitude. Here, it occupies a singular place which we call the marmots’  "bosse». This hibernating rodent is only visible between April and October. The marmot lives in a family and respects a hierarchy. Games, grooming, fighting and biting ensure the dominance of a couple as well as the cohesion of the group. Each animal participates in the delimitation of the territory by rubbing its cheeks on rocks and also by urinating and defecating there. When there is danger, the marmot emits a high and powerful whistle in order to warn the others.

  Felwort

  In early August, the felwort’s violet stars open in the sunshine. At the base of each of its five petals, two shiny pits full of nectar attract insects. A member of the gentian family, this beautiful flower is a perennial that survives the cold season with its persistent winter bud close to the ground, surrounded by a rosette of protecting leaves.

  Skylark

  This bird is like a tightrope walker suspended in the sky, sounding out a long chorus of notes. Then, triangular wings back, and in a perfect spiral, the bird lands in the middle of the prairie. On the ground, it is difficult to see: its varying shades of brown means it is very well camouflaged. In its search for food, its movements, which are a succession of small sprints and sudden halts, enable it to spot possible predators.

  Grey wagtail

  The grey wagtail elegantly hops along the rocks at the riverside. They are found in mountain streams, but also near all waterways in the mountains, in the countryside or in towns, and even small high-altitude lakes. Like other wagtails, they continually wag their long black tails edged with white. They have yellow breasts like the western yellow wagtail, but their backs are ash grey. In the mating season, males proudly show off their black throats, making it easier to tell them apart from females, whose throats and breasts are partly white. Their pinkish claws are specific to the breed, since other wagtails’ claws are black.

  Butterflies and moths

  Butterflies can be distinguished from moths by the shape of their antennae. You will also notice that when resting, the butterflies wings are vertically folded over the body for necessary discretion while the moth's cover them. The moorland clouded yellow butterfly has another unusual habit: as soon as it becomes too cold to fly, it settles and bends its side to the sun to absorb energy. It can even lean slightly, whereas others tend to fully, and dangerously spread themselves out.

  Moorland clouded yellow

  The heath surrounded by heather and willows is the home of a population of unusual and protected butterflies: the moorland cloud yellow. Elsewhere, it lives in different environments, such as blueberry heaths and peatland, where the moorland clouded yellow is rare and hard to spot. It can be recognised by its yellow display delicately sprinkled with grey under the rear wings of the male, while the female of the species has adopted almost purely white wings. They both wear a simple pink border highlighting the edge of their wings, with a tiny white ocellus (eye) encircled with brown and a discrete grey crescent.

  Alpine citril finch

  A small green-yellow-grey bird sways on a tall branch. Chet! The Alpine citril finch flies off to land on a scrap of threadbare grass. It looks like a small greenfinch, but the strident cry it makes during its short flight clearly sets it apart. Its head and breast flanks are a pretty blue-grey colour. Its yellow wing stripes can be easily seen. When flying over longer distances, its undulating flight is reminiscent of a goldfinch’s. And just like its cousin, the finch is sociable and moves about in small groups when exploring some sparse group of nettles or grass.

  Ring ouzel

  In the pastures covered with larch or 'bush", a cry of alarm followed the start of a song resounds. A blackbird? Yes, but more specifically a ring ouzel. This shy, swift mountain blackbird lives on the fringe of the larch, scots pine, spruce or Swiss pine forests between 1000 and 2500 m in altitude. The ring ouzel is a migratory bird that spends winter in Spain or North Africa before coming back to the mountains around March.

  Larch

  The larch is the only European resinous tree to lose its needles in winter. Its wood is red-brown. It stands out in the landscape with its leaves ranging from a soft green colour in spring to gold in autumn. Its pink flowers attract naturalists and photographers in the spring. The larch tree is a coloniser of mountain slopes. Although it is at home in the harsh conditions of the mountainside, it cannot bear competition from other trees. The Petit Tabuc site is a fine example of its colonising capacity, even though it is regularly hit by avalanches.

  A flying predator

  The eagle is the archetypal predator. Everything about it suggests strength and daring. Its appearance, of course, with its impressive expression highlighted by the prominent brow ridge, but above all its fearsome weapons: rapid flight, which can be adapted to even the most acrobatic situations, and sharp, powerful talons. Its keen eyesight helps it detect its prey, from the marmot to the young chamois, ptarmigans and hares. In winter, it often takes its food from the dead bodies of animals, helping towards the natural cleansing of nature.

  The Petit Tabuc site is ideal for the golden eagle to nest. The golden eagle is amongst the protected species that are considered rare in Europe.  The size of the populations that have been registered in the Ecrins massif, bestow a strong responsibility on the Park for conservation of the species. Counting takes place regularly since 1985 along with monitoring of reproduction, causes of disturbance and mortality.

  Golden eagle

  Near the mountain slopes, in the warmest hours of the day, a large bird circles in the sky, making use of the wind to climb. Soon the brown silhouette disappears into the blue sky, hidden by the altitude. The eagle patrols its vast territory, and no detail escapes its legendary eyesight. It also spends long hours perched and still, cleaning its plumage or looking out for its next victim. Although it steers clear of man, it is still quite easy to spot a royal eagle alone or with its “other half”, since adults generally live in couples. Its large size, dark colour, rectangular wings and frequent flights across the sky make it almost a familiar sight for anyone who knows how to “watch” the mountains.

The master of this little world is a small brown, red and grey bird with a short tail and a pure white breast, separated from the darker abdomen by a light brown stripe. We can often see it in the air, flying close to the water to snap up insects. The dipper owes its name to its eating habits to find water larva, it dips its head into the water and grips the riverbed to walk against the current.

  European badger

  You will often see a badger at nighttime on the edge of a path, a road or an embankment. The gentle pace and portly gait of this member of the mustelid family are reminiscent of a small bear you may get a glimpse of his black and the white stripes on his head before he hurries away. Worms, reptiles, frogs, fruit and plants are his staple diet. Families of badgers live in sometimes very extensive and very old burrows, with numerous chambers and galleries. They are tolerant animals, since they will sometimes share their home with rabbits and foxes. Badgers are among the unobtrusive neighbours whose presence goes undetected, except for their footprints made up of five nearly parallel toes and the tracks of their long claws.

  Lover of old stones

  The rock sparrow is a sedentary bird. It generally settles in well-exposed, agricultural areas where there are lots of stones, stone terraces, ruins, piles of stones, old buildings. This southern sparrow can be found up to an altitude of 2000 m provided there is an open landscape and many mineral elements. It nests in the hole of a rock, in a wall and sometimes under the roof of a house. It will then mingle with the house sparrow. A sociable bird, it lives in small, dispersed colonies.

  Whiskered bat

  The whiskered bat is a dark-faced bat. It is quite common in certain mountain regions and is one of the most frequent species after it cousin the common pipistrelle. It likes trees, be they on the banks of a river or in the high altitude forests, but it is also possible to catch sight of them in gardens and villages such as the hamlet of Casset. This small mammal lives on flying insects and thus helps in controlling their numbers. Like all mammals, the female feeds her sole offspring with her milk.

  Doors and courtyards

  As you stroll through the streets of Le Casset, some house doors will attract your notice, as they bring together most of the decorative elements of the facades. Made of larch wood, they have been moulded or sculpted with geometric or floral patterns and have a tympanum above them, often with a grating. Behind the door is the courtyard, the shared entrance for people and animals. The way people lived and organised their homes resulted in this single entrance, an area giving access both to the stable and to the living quarters. Between the world inside and outside, the courtyard provided a passageway, insulation, but also storage space.

  Rock sparrow

  The rock sparrow is here at the north-western limit and highest altitude of its home territory and regularly nests in the area. The species is in decline nationally and is on the endangered ‘red’ list in Rhône-Alpes and is being studied in the PACA region. People sometimes pay little attention to house sparrows since they are so familiar, which is a pity. The rock sparrow is bigger and although its plumage is similar to a female house sparrow’s, its call sets it apart at once: pi-yip or pi-yui or even a chay sound that is similar to a brambling’s!

  Le Casset

  At the entrance to the valley, Le Casset is a stone shell village surrounded by farming landscapes. Its name comes from the verb 'cassare' ('to break, to shatter' in late Latin), describing a place covered with stones. In fact there are many such villages in this mountain valley carved out by a vast glacier. Le Casset, on the left bank of the Guisane, is sheltered from avalanches beneath the watchful eye of the prestigious summits and glaciers that “move” in a different time scale from our own.

  Saint Claude’s church in Le Casset

  With its disproportionately high spire, the Casset church never goes unnoticed. Its four-sided Comtois steeple was modelled on the collegiate church in Briançon. The church is listed as a Historic Monument and is placed under the protection of Saint Claude. In its present condition, it dates from the 18th century. The previous building was constructed prior to the 16th century. Inside, the eye is immediately attracted by the choir ogives, creating an intimate atmosphere, particularly since the unusually large spire does not suggest an interior of such a small size. The choir was rebuilt in 1716-1717, probably after the previous chapel burnt down. Traces from this period can be seen on the keystone. The wrought-iron choir gate has the inscription "HM 1717", a date that can also be seen in the apse, on the wrought iron railing of the impost of the axial window, and on the baptismal font.

  Pastoralism

  The old hay meadows

  Lower down as you cross the area, near the pastoral Cabane de l'Eychauda, you can make out piles of stones, the clapiers formed by the removal of stones from the hay meadows. In order to feed the livestock right through the winter, it was necessary to garner a large amount of hay! With changes in livestock farming practices, there are no longer cut for hay, but used for grazing. Only a tiny area of the valley - the flattest - is still mown for hay, mechanically.

  Geology and geography

  The front of the nappes

  The two slopes of the Chambran valley are very different: the right bank, minerals are very present. There are granites and gneiss making up the crystalline base of the Ecrins massif. On the left bank, the prairies are sandstone and chalky. These are part of the glacial thrust sheet: they are ancient sediments deposited mostly to the East, in the Alpine ocean, then carried here by compression at the time of the formation of the Alps.

  Evolution of pastoralism

  In the valley, the ruins of numerous piles of stones resulting from the removal of stones in the hay meadows are witness to another age. Most of these old prairies are now grazed by sheep. Pastoralism has evolved: no more local flocks so less hay, the valley is now occupied by a large flock from the Haute-Provence Alps.

  The realm of sheep

  Together with its entire catchment area, the Chambran valley constitutes an enormous alpine pasture. Sheep belonging to several different owners are gathered here for the summer grazing season. Many of them come from the department of Alpes-de-Haute-Provence. The landscape (sheep paths, old hay meadows), vegetation, built structures (old dairy, pastoral cabins)... everything has been marked by centuries of animal husbandry.

  The Gyr

  Humans are decidedly bizarre animals: they build, knock down and start again. To protect the new infrastructures of Pelvoux, the Gyr was dammed. But, not able to flow as it did before, it deepened its bed, thus placing the foundations in danger of damage. And so works were carried out to widen its bed, allowing it to flow more naturally. This is also more favourable for biodiversity, as well as protecting the developed urban areas.
