Aiguille
AIGUILLE (Fr. for needle), the sharp jagged points above the snow-line, standing upon the massif of a mountain split by frost action along joints or planes of cleavage with sides too steep for snow to rest upon them. Aiguilles are thus the forms remaining from the splitting up of the high ridges with houseroof structure into detached pinnacles.
