Although they move slowly, glaciers do move, and this movement alters the ice as it passes over land. Likewise, a moving glacier can carry with it evidence of geologic events it has witnessed. The Bear Glacier in the Kenai Peninsula along the Gulf of Alaska bears multiple clues about its past.

This photograph of Mt. Kazbek was taken from the International Space Station on August 13, 2002. The astronauts and cosmonauts took the photograph at the request of the Russian URAGAN Project, which is studying changes in the world’s glaciers in response to global climate change. Although scientists have predicted the possibility of large glacial collapses as the climate warms, no one predicted that tragedy would strike the mountain village of Karmadon, a little more than a month later.

The Southern Patagonian Icefield of Chile and Argentina hosts several spectacular glaciers—including Grey Glacier located in the Torres del Paine National Park in Chile. This glacier, which in 1996 had a measured total area of 270 square kilometers and a length of 28 kilometers (104 square miles in area, 17 miles long), begins in the Patagonian Andes Mountains to the west and terminates in three distinct lobes into Grey Lake (upper image).
