Cirque glacier
（重定向自Corrie glacier）
A cirque glacier is formed in a cirque, a bowl-shaped depression on the side of or near mountains. Snow and ice accumulation in corries often occurs as the result of avalanching from higher surrounding slopes. If a cirque glacier advances far enough, it may become a valley glacier. Additionally, a valley glacier retreats enough that it is within the cirque, it is a cirque glacier again.
