Saint Christophe Formation

The Brèches du Grand Fond Group is a group of stratigraphic formations in France that were deposited between the Middle Jurassic and the Early Cretaceous. The deposition was contemporaneous to the rifting of the Valais ocean, and overlies the pre-rift rocks along an angular unconformity. The Brèches du Grand Fond Group is overlain by the post-rift sequences Couches de l’Aroley, Couches des Marmontains and the Couches de Saint Christophe.The Brèches du Grand Fond Group consists of two formations that are found in the External Valais units, the younger Pyramides Calcaires Formation and the older Dent d'Arpire Formation. The deposition of these two units was roughly contemporaneous to the deposition of the Brèches du Collet des Rousses and the Complexe Antéflysch Formation of the Internal Valais units.In general the Brèches du Grand Fond Group consists of coarse grained clastic sediments composed of pre-rift lithologies. Outcrops can be studied The Brèches du Grand Fond Group can be found within the following nappes: External ValaisMoûtiers unit Roc de l'Enfer unitOutcrops occur to the northwest of Bourg-Saint-Maurice.

The Couches des Marmontains are a sedimentary formation deposited during the middle Cretaceous (Albian to Cenomanian). It consists of sandstones and black shales. The formation is 5 to 30 m thick. The Couches des Marmontains overly the Couches de l’Aroley and underlie the Couches de Saint Christophe. All three units together make up the post-rift sequence of the Valais ocean. Outcrops can be found north of Bourg-Saint-Maurice.The Couches des Marmontains can be found in the following nappes: External ValaisMoûtiers unit Roc de l'Enfer unit Petit St. Bernard unitInternal ValaisVersoyen unitThe type locality and namesake of the formation is the mountain Marmontains (45.88263°N 7.108412°E / 45.88263; 7.108412) and the Val Ferret in Orsières, Canton Valais, Switzerland. It was first described in 1955 by Rudolf Trümpy.The Marmontains Formation can be correlated with the Valzeina Formation of Graubünden and black shales in the Engadine.

The Couches de l’Aroley (short: Aroley Formation) are a sedimentary formation deposited during the Early Cretaceous (Barremian to Aptian). They consist of calcitic schists with dolomite clasts interbedded with finegrained conglomerates. The whole sequence is about 100 m thick.The Couches de l’Aroley are the lowest of the three post-rift sequences deposited in the Valais ocean. It overlies syn-rift sequences of the Brèches du Grand Fond Group.The Aroley Formation can be found within the following nappes: External Valais Moûtiers unit Roc de l'Enfer unit Petit St. Bernard unit Internal Valais Versoyen unitThe type locality is the Massif de la Pierre Avoi, in Saxon, Valais, Switzerland. The formation is named after a "Plan Aroley" which lies below the Pierre Avoi. It was first described by Rudolf Trümpy 1952.The Couches de l’Aroley can be correlated with the Klus Formation and the Tristel Formation found in eastern Switzerland, the Engadin window and the Tauern window.

The canton of Bourg-Saint-Maurice is an administrative division of the Savoie department, southeastern France. Its borders were modified at the French canton reorganisation which came into effect in March 2015. Its seat is in Bourg-Saint-Maurice.It consists of the following communes:

Tignes – Val d'Isère is the combined ski resort area of Val d'Isère and Tignes in the Tarentaise Valley, Savoie in the French Alps. Formerly known as Espace Killy, in honour of the spectacularly successful skier Jean-Claude Killy who was raised here.There are claimed to be 300 km of pistes: 22 green runs, 61 blues, 46 reds and 25 blacks, plus 44 km of cross country skiing 2 terrain parks 2 glaciers 90 ski lifts

Bourg-Saint-Maurice (French pronunciation: [buʁ sɛ̃ mɔʁis, - moʁ-] ; Arpitan: Bôrg-Sant-Mori or simply Le Bôrg), popularly known as Bourg, is a commune in the Savoie department in the Auvergne-Rhône-Alpes region in south-eastern France. Located on the Italian border south of Chamonix-Mont-Blanc, it had a population of 7,252 as of 2018. It serves as a transport hub for the Paradiski ski area, with direct rail travel from London (Connecting in Lille), and Amsterdam during the winter.

Bourg-Saint-Maurice station (French: Gare de Bourg-Saint-Maurice) is a railway station in Bourg-Saint-Maurice, Auvergne-Rhône-Alpes in south-east France. The station is located at the end of the St-Pierre-d'Albigny-Bourg-Saint-Maurice railway. The station is served by TGV (high-speed long-distance) and TER (regional) services operated by SNCF. During the winter months Eurostar services from Amsterdam, Brussels and Lille travel to Bourg-Saint-Maurice. The station was heavily rebuilt for the 1992 Winter Olympics in Albertville. The station also features some sidings to store passenger trains when not in use. Juxtaposed controls are in fitted in the station for Eurostar passengers travelling to the United Kingdom (a routing not currently in service). Passengers clear Schengen Area exit checks (carried out by Customs officers) as well as UK immigration entry checks (conducted by the UK Border Force) in the station before boarding their train on a secure, gated platform.

Ouvrage Cave-à-Canon is a lesser work (petit ouvrage) of the Maginot Line's Alpine extension, the Alpine Line. Started in 1937, the ouvrage consists of one infantry block about one kilometer east of Bourg St. Maurice, on the south bank of the Isère. A short gallery with cross galleries extends into the rock, with an emergency exit and ventilation shaft halfway back. The ouvrage was incomplete in 1940, under the command of Lieutenant Courteaud.Cave-à-Canon, and with Ouvrage Chatelard across the valley to the north, and several pre-1914 forts on the heights around Bourg-Saint-Maurice, were placed to block an advance over the Little St Bernard Pass toward Albertville.
