  Fauna

  Large Blue Butterfly

  This butterfly with blue wings spotted with black frequents the mountain grasslands and entrusts the ants with rearing its caterpillars... It lays its eggs on the host plant, the Breckland Thyme, whose flower buds feed the caterpillar until it lets itself fall to the ground. The Fire Ants take over. They are attracted by the honeydew produced by the caterpillar and they transport it to their anthill to milk it. . The caterpillar becomes carnivorous and eats the young ant larvae without being disturbed. It hibernates until the Spring. When it reaches maturity, it creates a chrysalis in the anthill. The butterfly hatches and quickly goes out in to the open air to carry out the reproduction of the species.

  Panorama

  Conquest of the Ailefroide

  By its magnitude, its height, its steepness, the conquest of the North-West face of the Ailefroide (impressive view of the North-West face of the Ailefroide which dominates Carrelet plain at an altitude of 3954 m) it is comparable with the famous Northern face of the Grandes Jorasses by Devies. The first ascent carried out by the corded team Devies and Gervasutti on the 23rd and 24th July 1936. On the approach from the Temple-Ecrins refuge Gervasutti broke a rib which did not stop him from carrying out this prestigious first.

  Flora

  Mountain Pine pinewood

  The pinewood of Mountain Pines at Carrelet is rightly considered to be the highest in Europe. In fact, it occupies a slope at an altitude of 2400 m. It is also developing downwards due to the end of pastoral bovine activity at the beginning of the 1970s. Progressively, the grassland has been colonized by the juniper heath which encourages the implantation of Mountain Pine.

  Flora

  Mountain Pine

  The Mountain Pine is a high altitude species. This tree can be seen on the sunny slopes up to an altitude of 2450 m. If it can reach a height of 15 m locally it becomes much shorter and crooked even bushy when conditions are difficult... Its roots are solid, it is a frugal species that can support a very short vegetative period, extreme cold, snow, drought, the alpine brightness, the wind and the black ice,. It can be used as a species for reafforestation at altitude with a view to protecting certain soils and to fight against the beginning of avalanches...

  Panorama

  Plan du Carrelet

  At the meeting point of the Vénéon and Chardon valleys, the Plan du Carrelet is a vast plateau of glacial origin. It was originally a lake, after the glaciers withdrew, and was then gradually blocked by sediment coming down from the slopes all around, forming the vast plateau that can be seen today. Fed by the many mountain streams flowing into it, it is exceptionally rich in plant life, particularly species that are at home in wet and turbulent environments, like the banks of a mountain stream. In early summer, the plants bloom, providing an impressive sight , in the midst of the mountain pines, replanted at the beginning of the 20th century by the foresters, and which are now the prevailing species.
  The Carrelet Refuge standing in the middle of the plateau was one of the oldest refuges set up by the Club Alpin Français, and dates from 1879. It is now a private residence and closed to the public.

  Know-how

  Upkeep of the slopes and paths

  The Restauration des Terrains en Montagne (RTM, "Restoration of Mountain Land") service, now part of the ONF, has been carrying out civil engineering work to combat erosion in the ravines near the path leading to the Temple-Ecrins refuge since 1882. Permanent monitoring and major annual maintenance work are needed to maintain thresholds, wire-mesh fencing, planting indigenous species and laying turf. Each year, the park rangers set up temporary walkways across the mountain streams.

  Pass

  High attitude passages

  The Col de la Temple (to the east of this trail), at an altitude of 3,322 m, constitutes a relatively easy passage between the Vallouise and the Vénéon. The last access slope to the pass is occupied by a small glacier that has greatly diminished in size in recent decades. The pass seems to be free of ice, but the ice is actually hidden by the stones. The story goes that once, a priest managed to go through the pass from the Vallouise to say mass at La Bérarde. Today, the pass is mainly peopled by mountain-climbers on their way to Pic Coolidge, standing at 3,774 m.
