Reculée de Montagna-le-Reconduit

The plateau is sometimes hollowed out by narrow valleys that run across the relief line. These valleys end in a cul-de-sac, where the underground water that has infiltrated the limestone plateau resurfaces.
Montagna is located in a recess of the Revermont, western fold of the Jura mountains, at the foot of the first Jura plateau, and east of the Bresse plain. The river Besançon has its source at the bottom of the valley.
