The Collet de la Salcette (trail route no. 10)

In spite of the altitude, the region's dry climate and the local growing conditions of limestone and sediments facing due south made the planting of grapevines possible as far back as the tenth century. The municipality owes its name to the presence of these vineyard operations, which were very significant in the late nineteenth century. The almost simultaneous appearance of the phylloxera aphid and the Briançon train, bringing wine from Provence, spelled the end of this activity here.

Malgré l’altitude, le climat sec de la région et un terroir de calcaire et d’alluvions orienté plein sud ont permis l’implantation de vignes, ce dès le Xème siècle. Le nom de la commune a pour origine la présence de ce vignoble qui fut très important. À la fin du XIXème siècle, l’arrivée quasi simultanée du phylloxera et du train à Briançon, transportant du vin de Provence, mit fin à cette exploitation.

The path offers a beautiful overall view of the limestone massif of Montbrison, overlooking the hamlets of Pelvoux and including the Cime de la Condamine, the Tête des Lauzières, the Pic de Montbrison and the Tête d'Amont.

Very shy, this large lizard quickly takes refuge beneath a bush or stone, or among the tangled branches of a hedge when it senses danger. It is on average 30 cm in length and it is bright green slightly speckled with black. During the mating season, the male presents a bright blue colouring on his throat and on the sides of his head. It lives on sunny south-facing slopes, in uncultivated areas and forest edges, where it feeds primarily on insects.

In March, this large brown bird of prey, brown on its upperside, white speckled with black on its underside and a dark head, returns from Sub-Saharan Africa where it has spent the winter. It feeds primarily on reptiles which its hunts in steppe or barren areas, derelict sites or stony terrain. It builds its nest in a pine tree where it will rear a single chick. It can often be seen hovering in the air, thirty or so metres above the ground, and then swooping down on its prey.

Bouchier is a small hamlet in the municipality of Saint-Martin-de-Queyrières, which has a few permanent inhabitants in spite of its relatively inaccessible location. Standing a little apart from the hamlet, on a promontory overlooking the Durance valley, the chapel of Saint-Hippolyte dates from the early sixteenth century. It was built against what used to be a hermit's cell, and contains frescoes some of which relate the miraculous cures performed by the saint. It drew ailing people who flocked here to seek his intercession. 

Bouchier est un petit hameau de la commune de Saint-Martin-de-Queyrières qui, malgré son accès difficile, accueille quelques habitants permanents. Située à l’écart du hameau, sur un promontoire dominant la vallée de la Durance, la chapelle Saint-Hippolyte date du début du XVIème siècle. Elle est accolée à ce qui fut une cellule d’ermite et abrite des fresques dont certaines relatent des guérisons miraculeuses effectuées par le saint. Elle attirait les malades venus demander son intercession. 

This member of the Gramineae family (now called Poaceae) forms large clumps on stony, dry and sunny ground. It grows in abundance here on the track embankment, taking advantage of the sunlight allowed through by the break in the forest. Its inflorescences reflecting silvery-gold glints are made up of flowerets with long edges. They create a very misty effect in the late summer when the plant is mature, forming large shimmering bouquets in the evening sunlight. . 

The highlight of this trail, overlooked by the southern, colourful foothills of the Montbrison massif (Tête d'Aval, Tête d'Amont, Les Tenailles), the Croix de la Salcette offers both the gentleness of a vast alpine grassland and a splendid panorama of the upper reaches of the Durance valley. 

This small black corvid sports a yellow beak and red legs. It likes to fly in groups of several dozen or even several hundred individuals. Common in the mountains and a great acrobat, it can often be spotted whirling around cliffs or skimming over the alpine grasslands. It often hangs around picnics to gather up the crumbs!

At the approach of intruders, rock partridges fly away with a great whirring of wings from the rocky ground where they had hitherto passed unnoticed. This bird favours south-facing slopes which are rocky and well exposed to the sun. During the mating season, at dawn the male produces an echoing, rasping and rhythmic call. It is a species in sharp decline.  

On peut observer des aigles planant autour de la Tête d’Aval, qui bénéficient, aux heures chaudes de la journée, de l’air s’élevant au-dessus des falaises calcaires. Ayant ainsi pris de l’altitude, ils peuvent aller rejoindre leur territoire de chasse sans donner un coup d’aile.

Elle est présente toute l'année, profitant en hiver des nombreuses baies du gui poussant sur les pins. En été, ce sera plutôt insectes, escargots ou vers pour le repas. En hiver, elle se déplace souvent en petites troupes pleines de cris d'alarme : trrrrrrrrr, trrrrrrrr. Dès le mois de mars cependant, les mâles lancent leur chant flûté ressemblant un peu à celui du merle.

Un drôle d’insecte mi-papillon mi-libellule, aux grandes antennes noires, aux ailes transparentes teintées de jaune ou de blanc et aux nervures bien marquées, vole sur la prairie aux heures chaudes de la journée. C’est l’ascalaphe soufré. Les ascalaphes font partie de la famille des névroptères et sont cousins des fourmilions et des chrysopes. Ce sont des prédateurs de petits insectes, surtout des mouches. 

Eagles can be seen gliding around the Tête d'Aval. In the hottest part of the day, they circle on the thermals rising above the limestone cliffs. Having gained height in this way, they can reach their hunting territory without having to flap their wings.
