Peter Knight photographed various glaciers around the world including niche glaciers in Wyoming that are sensitive to climate change, the ice cap on Cotopaxi volcano in Ecuador which extends further on the windward side due to higher snowfall, and valley, mountain, and ice sheet glaciers in locations such as Alaska, Greenland, and New Zealand. The photos show glacial landforms and features including moraines, crevasses, ice caves, supraglacial streams, ice cliffs, striations, and erratics.

2. Niche glaciers
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.

3. 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.
