Grotte de la Tassonière

The main gallery has a low entrance, an entrance gallery, a wall, a large fault, passages to the left and ahead, a narrow passage leading to a fine gallery, a low gallery ending in a descending squeeze, an intersection and a low point where the galleries seem very narrow.

From the low entrance, the airflow is always followed. After the entrance gallery, one comes up against a wall: the way on is to the left, where one climbs up to reach a large fault. Passages present themselves to the left and ahead. The way on is behind us: the fault is climbed by a narrow passage that leads to a fine gallery, which is descended. It quickly ends at a low gallery that finishes in a descending squeeze; the passage is done without difficulty… if you do not have your harness. The descent continues; at the next intersection, one goes left to arrive at a low point where all the galleries that present themselves seem very narrow. The airflow indicates that one must go through the ceiling to find a gallery with a few narrow passages without difficulty.
