The col of glaciers is between the glacier of Ossoue (south, our side in the image) and glacier of Petit Vignemale (in the other side). It's an important place in the rock-climb of the ridge Petit-Grand Vignemale:
-right side: summit of Petit with the descent (A.D.inf.) to col.
-left side: ridge of Pointe de Chausenque (P.D.).
