Our ancestors, those trail runners (trail route no. 6)

The common barberry is a bush with long thorns arranged in threes, and with oval serrated leaves. In spring, it produces clusters of yellow flowers, which later develop into red, oval and elongated berries. These tart fruits are edible and can be made into jellies... if you have the patience to gather them! This shrub grows almost everywhere.

Elle correspond à une zone de surcreusement lors des glaciations : le glacier freiné par le verrou de roche dure de Pallon, a creusé une dépression. Au retrait des glaciers, un lac est resté coincé derrière ce verrou, peu à peu comblé par des alluvions. C'est maintenant un espace agricole facilement mécanisable.

The valley was created as the result of glacial overdeepening, that is to say, when the glacier came to a halt against the Pallon hard rock bar, it created a depression. When the glaciers retreated, a lake was left behind this rock bar and was gradually filled up by alluvial deposits. From a historical point of view, the Protestant pastor Félix Neff fundamentally altered life in the valley in 1826 by founding a training college for primary school teachers, developing irrigation processes and teaching new crop growing methods, among other things…

Perché sur un bloc au milieu de la rivière, un oiseau trapu, à la queue courte, brun avec une grande bavette blanche, se balance de haut en bas avec la queue dressée. Puis il plonge et ne réapparaît que quelques instants plus tard. Cet oiseau chasse ainsi, plongeant puis marchant à contre-courant au fond de l'eau en quête de larves aquatiques d’insectes, de petits crustacés ou petits poissons, soulevant les galets avec son bec pour les déloger. 

The ditches on the Freissinières plain are edged by a plant with very broad leaves: the petasites hybridus or butterbur, also called the devil's hat in French. In Ancient Greek, the petasos was a round felt hat. Nobody knows whether the devil wears this hat, but the plant is certainly used as a herbal remedy. Very common in the lowlands, it is quite rare in the Pays des Écrins although other species of petasites do grow at higher altitude.   

D’avril à juin, un chant d’oiseau bien peu mélodieux, un trille court et sonore, retentit dans la forêt. C’est celui du pouillot de Bonelli, revenu de migration. C’est un oiseau au plumage assez terne, vert olive avec le ventre blanc. Bien pratique pour se dissimuler dans les branches mais beaucoup moins pour se faire remarquer par une femelle. Une seule solution : chanter fort ! Il vit dans les forêts claires et les landes sur les versants chauds.

A low spreading shrub, the savin juniper is very common in stony meadows and uncultivated land on warm slopes. Its dark, matte green leaves in the form of small scales, overlap along the branches. So it isn't spiky... but you still need to be cautious as it is very toxic. For seasoning dishes, better to gather the fruits of the common juniper!

The hamlet of Pallon is in a sunny location. Around the village, a curious plant with long brown trumpet-like flowers grows on the edges of the stone piles in the fields and meadows: the aristolochia pistolochia or birthwort. Of Mediterranean affinity, this plant benefits from the hot dry climate here and is virtually at its northern boundary. It is the host plant of the caterpillars of a rare and protected butterfly: the Spanish festoon. 

This small tree is present in North Africa, the Iberian Peninsula and in a few departments in southern France, including the Hautes-Alpes. It is regarded as a relic from a warmer period far back in history. It has found a refuge in well exposed situations, on warm sunny slopes. Its needles are in the form of scales, lying against the branches. It is a monitored species.

In ancient times, the Durance valley was a key communication corridor. Rama was a kind of staging post on the Roman road. In the Middle Ages, Rama was a small town with a noble's château. But the village was devastated by the capriciousness of the Durance and the Biaysse rivers on numerous occasions and the inhabitants gradually deserted the site, moving to neighbouring villages. The attachment of the parish of Rame to that of La Roche in 1446 is indicative of this decline.

À l’époque des grandes glaciations, l’énorme glacier de la Durance a creusé son lit sur une épaisseur de plus de 200 m de haut. Le glacier de la vallée de Freissinières affluait à la surface de ce glacier. Leur fonte a laissé une grosse “marche d’escalier” nommée gradin de confluence. La Biaysse rejoignant la Durance, a peu à peu creusé ce gradin, d’abord en tant que torrent sous glaciaire puis après la fonte du glacier.

Protected from Atlantic influences by the Massif du Pelvoux, the high Durance valley has a very dry climate with wide seasonal temperature fluctuations. It has grasslands very similar to the steppes of Central Europe which are rare in France. It is part of the Natura 2000 “Steppique durancien et queyrassien” (Durance and Queras valley steppes) site.

The Sentier du Gouffre has sometimes been described as a Roman road, but we do not know the exact route the Roman road followed. One thing is certain, it used to be used by the villagers to reach their fields and vineyards, and for any other journeys they had to make.

Numerous butterflies can be seen enjoying the sunshine along the way. One is very easy to recognise. Completely black and white, maybe the person who gave it its French name demideuil («half in mourning) was a pessimist! In England, however, its name "marbled white" puts the emphasis on its white colour. It is a common butterfly and its caterpillars feed on grasses. 

This hamlet of just a few houses is in the municipality of Champcella. The name Faure is common in the south-east of France and originates from the Occitan language. It means blacksmith. It is also frequent in place names, and there are many places called «les Faures», where the blacksmith lived.

Emblème des Alpes du sud, ce résineux perdant ses aiguilles en hiver, se pare d’or et illumine la montagne à l’automne. Les mélézins sont entretenus par le pâturage des troupeaux. Sans eux, d’autres arbres comme le sapin ou différents pins peuvent pousser pour donner un autre type de forêt. Espèce pionnière, le mélèze ne craint pas la lumière pour s’installer. Son bois résistant et imputrescible a toujours servi pour la construction des maisons.

Here, the drought-sensitive fir has established itself among the larches. This forest harbours treasures such as the very rare ghost orchid and the shield-moss, a unique little moss - also rare - which grows on wood in an advanced state of decomposition and thus signals that the natural cycle of the forest is unimpaired.

On the banks of a stream, on the edge of a ditch a plant grows which resembles a large bottle brush... or a horse's tail, depending on your imagination. It's the field horsetail, a plant related to ferns. It is known for its medicinal properties because it is rich in silica, a powerful remineraliser for the bones, cartilage and skin. There are several species of horsetail. 

Elegant and alert, a squirrel crosses the track, followed by its long feathery tail. Red? This one is dark brown. In the mountains this rodent has adopted a “solar panel” strategy, on the principle that dark colours absorb the heat more efficiently. It is active during the day and does not hibernate, although it does minimise its activity on days when the weather is bad. It is a protected species.

The fir thrives on this north-exposed slope, called the ubac. Its needles have two white stripes on their undersides. They are arranged on either side of the boughs, and not all the way around them, which distinguishes it from the spruce. The elongated cones stand upright, rather than hanging downwards. They grow in large number, often mingling with larch trees under whose shade they can grow. By contrast, the larch - the "tree of light" - cannot grow under the cover of fir trees.
