The Grand Som Martel is part of a Jura chain that extends in a south-west-north-east direction from the basin of Saint-Sulpice over the Trémalmont and the Crêt du Cervelet to Mont Sagne near La Chaux-de-Fonds. With its two peaks ( 1337  m and 1331  m above sea level ) it forms the highest point of this chain. The ridge is bounded in the southeast by the wide basin of the Vallée des Ponts , in the west by the lowlands of the Vallée de la Brévine and in the north by the basin near Le Locle .

On the Grand Som Martel there are extensive Jura high pastures with mighty spruce trees , which either stand individually or in groups; steeper slopes are wooded. The ridge of the Grand Som Martel is a hiking area. In winter you can go skiing here; There is a ski lift on the northern slope of the mountain.


In structural geological terms, the Grand Som Martel forms an anticline of the Jura folds . The mountain top is made of competent limestone from the younger Jurassic period ( Malm ). At weak points, the vault of the anticline was attacked by erosion and removed, so that the marly effinger layers underneath were exposed. For example, the Entre deux Monts basin to the northeast and the Combe des Sagnettes to the southwest of the Grand Som Martel were created.
