Tré la Tête Glacier by Combe noire Waterfall
The nature reserve
The bogs at la Rosière
Originating from the ice age, this wetland was first a depression eroded by the glacier in which the melting ice stagneted. It’s a paradise for carnivorous plants such as Alpine Butterwort or the Round-leaved Sundew...
The round-leaf Sundew
It is called "Rossolis or Sundew" because of the scintillation of this substance in the sunlight.
This species is fragile and protected, please do not touch it !
The roman bridge
This route, which has become the GR5 since, is a popular tourist destination.
The bridge overlooks the gorges of Bont Nant.
Admire the natural pools that the torrent has shaped slowly but surely!
Hay meadows at la Laya
Since 2014, the Nature Reserve has carried out brush clearing and later season mowing in order to restore this environment for autumn grazing.
The Alpine autumn Crocus
This plant contains a very toxic alkaloid: colchicine. According to alchemists, this substance, used in very low doses, would cure rheumatism and acute flares of gout.
This small diurnal bird of prey, is common but very discreet. It terrorizes passerines, an order including most songbirds, on which it feeds!
It is a predator using a special ‘surprising’ technic to hunt by flying as close as possible to the rock walls or hidden behind obstacles to startle its prey.
The waterfall of Combe noire
The Crested Tit
The belvedere of Combe noire
You overlook the forest and the hamlet of "Combe Noire". Its name refers to the forest cover composed almost exclusively of dark colored spruces.
From this amazing viewpoint, discover the pastures of La Rollaz crossed by the hiking trail. From the left to the right, you can see Roches rouges, Roches franches, Aiguilles de la Pennaz, Col du Bonhomme, Rocher du Bonhomme and at the end Tête Nord des Fours.
The Golden Eagle
His exceptional view can locate groundhogs (his favorite meal), hares, foxes or ptarmigans and sometimes even young chamois or ibexes!
Its brow line provides a natural sun shield when diving to capture its prey. It is fully equipped for these hunting technics, with claws called talons and a powerful, hooked and sharp beak for shredding flesh.
A glacier and humans
It is indeed surrounded by the mythical peaks of the Mont-Blanc massif such as Dômes de Miage or Aiguille Nord de Tré-la-Tête, the highest point of the nature reserve with an altitude of 3892 m.
It is the crossing point for many classic high mountain or ski mountaineering routes.
Since the end of the nineteenth century this place witnesses the evolution of mountaineering activities.
A water intake under the glacier
In 2011, the nature reseve, in partnership with EDF, carried out a program to dismantle the industrial infrastructures (dormitories and cable cars)linked to the creation of this water intake.
The glacier of Tré-la-tête
Its health, monitored by the nature Reserve since 2014, is determinated by the volume of ice gained or lost. This is called the mass balance.
8 km long, it spreads its tongue of ice from the mountain pass Infranchissable at the Italian border at 3300m of altitude, to the place where you are standing!
