La vallée des Chapieux est une vallée de France située en Savoie, entre le massif du Beaufortain à l'ouest et celui des Alpes grées à l'est, sur le cours du torrent des Glaciers, en aval du hameau des Chapieux. Cette vallée glaciaire communique vers l'aval au sud avec la vallée de la Tarentaise à Bourg-Saint-Maurice et vers l'amont au nord-est avec la vallée des Glaciers et le massif du Mont-Blanc et vers l'ouest avec le Beaufortain via le Cormet de Roselend.

The Pointe de la Terrasse is a mountain in the Beaufortain Massif in Savoie, France.

The Couches de l’Aroley are a sedimentary formation deposited during the Early Cretaceous. 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 unit
The 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 Couches des Marmontains are a sedimentary formation deposited during the middle Cretaceous. 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 Valais
Moûtiers unit
Roc de l'Enfer unit
Petit St. Bernard unit
Internal Valais
Versoyen unit
The type locality and namesake of the formation is the mountain Marmontains 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 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 Valais
Moûtiers unit
Roc de l'Enfer unit
Outcrops occur to the northwest of Bourg-Saint-Maurice.

The Couches de Saint Christophe are a sedimentary formation deposited between the Late Cretaceous and the Paleogene. It is a very monotonous sequence of calcitic sandstones and black schists. These are interpreted as a turbidite sequence. The average thickness of the unit is 500 m. The Couches de Saint Christophe are a post-rift sequence that overlies the Couches des Marmontains.
The Couches de Saint Christophe occupy the following nappes:
External Valais
Moûtiers unit
Roc de l'Enfer unit
Petit St. Bernard unit
Internal Valais
Versoyen unit
Large outcrops of the Couches de Saint Christophe crop out north of Bourg-Saint-Maurice.
The type locality of the formation is the Val de Bagnes in the canton Valais of Switzerland. It was first described by Rudolf Trümpy in 1952. The formation is named after a chapel to the northwest of Verbier.
The Saint Christophe Formation can be correlated with the Sassauna Formation found in Graubünden and calcareous flysch found in the Engadine.
Histoire
En août 1944, la vallée est le lieu d'un affrontement entre une unité de la Wehrmacht et des partisans des maquis de Tarentaise et du Beaufortain.
