Page 2: Glacial landforms

The smallest scale of glaciation: Niche glaciers and ice aprons in the Grand Tetons, Wyoming, USA. Small glaciers such as these are often the most sensitive to local climate change. 

Niche glaciers

The summit ice cap of  the volcano,Cotopaxi, Ecuador

The ice cap extends further on one side of the mountain. The side of the mountain facing the moisture-bearing winds has higher snowfall and hence more extensive glaciation. The deep channels carved by meltwater and by volcanic mudflows (lahars) caused by melting of snow and ice during eruptions.
