Geography

Location

The massif extends southwest of the Belledonne range and is located northwest of the Écrins massif, north of the Dévoluy massif, and east of the Vercors. It is bordered by the Drac, Romanche, Lignarre, and Malsanne rivers. The plateau Matheysin, along with the surrounding peaks, occupies the western half. The northeastern part, known as Plateau des Lacs, is dotted with mountain lakes such as Veche, Agneau, Noir, Culasson, and Fourchu. The northeastern fringe, encompassing the Lignarre and Romanche watersheds, belongs to the Oisans region.

The massif is classified as a Natura 2000 site, featuring 19 habitats of community interest.

Geology

The Taillefer massif is predominantly a crystalline massif, similar to the Belledonne, to which it serves as an extension. In contrast, the western chain of Sénépy and the Conest mountain consists of slightly clayey limestones from the Lower Lias period. Additionally, the western flank features outcrops of calcschists from the Upper Lias period.
