Mýrdalsjökull, south Iceland, “the ice cap in the marsh valley”. 
 
The ice-cap covers an active volcano called Katla. The crater of the volcano has a diameter of 10 km and the volcano erupts normally every 40 - 80 years.
 
As the last eruption took place in 1918, scientists are monitoring the volcano very carefully. Since 930, 16 eruptions have been documented.

Helheim Glacier, South-east Greenland. 
 
The Helheim glacier's rate of flow has increased from 8 km per year (5 miles per year) in 2000 to 11 km per year (6.8 miles per year) in 2005. In addition to flowing more rapidly the glacier thinned by 40 meters (130 feet) between 2001 and 2003. 
 
The calving front of the glacier has retreated by approximately 5 km (3.1 miles).

Kangerdlugssuaq Glacier, eastern Greenland 
 
Its rate of flow more than doubled between 2000 and 2005 reaching a speed of 14 km per year (1.6 meters per hour). 
 
It had been retreating 25 to 100 meters per year in the period between 1992 and 2000, retreated more than 4 km between April 2004 and April 2005.

Astrolabe Glacier, Adelie Land, French Antarctica. The glacier is 6 km wide and 16 km long. Its tongue is 4.8km wide and 6km long.

Barnard Glacier is a 53-km-long (33 mi) glacier in the U.S. state of Alaska. It trends southwest to the Chitina River east of Hawkins Glacier, 64 km (40 mi) southeast of McCarthy in the Saint Elias Mountains.

The glacier is named for United States Geological Survey surveyor Edward Chester Barnard (1863–1921), Commissioner for the United States for the defining and marking of the boundary between Alaska and Canada.

Dry Valleys, Antarctica. The McMurdo Dry Valleys are located within Victoria Land, west of McMurdo Sound, Antarctica. Their name is due to the extremely low humidity and their lack of snow or ice cover, which place the region as one of the world’s most extreme deserts. These conditions are caused by katabatic winds, which can reach 320 km/h, evaporating all moisture, ice and snow.

Mount Erebus, Antarctica. Located on Ross Island, Mount Erebus is the southernmost active volcano on Earth. Discovered on January 27, 1841 by Sir James Clark Ross, it now faces the McMurdo research station. Mount Erebus is 3794 m high.

Northern Patagonian Ice Field, Chile. SPOT 5 3D View over a portion of the Northern Patagonian Icefield in the Chilean Patagonia. Background, the San Valentín (also named San Clemente) Mount, the highest mountain of the Chilean Patagonia (4070m) and also the highest mountain south of 40°S, apart from the Antarctic ranges. Halfway, the accumulation areas of the two largest glaciers of the ice cap, San Rafael and San Quintín, which have shown a fast acceleration of their retreating and shrinking in the past decades. Foreground, the San Quintín glacier, which terminus is a piedmont lobe just short of the Golfo de Penas on the Pacific Ocean.
