In polar and other cold regions there are ice, snow and water formations that are unusual, unique, and some of them so beautiful they take your breath away. Most of these wonders of nature can be visited only by scientists and rare adventurers who are ready for significant physical and financial exertions. Because of their volatility and locations, these formations can be seen only at certain periods of the year.
# Blue River, GreenlandThis river is a kayaking heaven in Greenland. The melting Petermann Glacier fill up the low lying areas with stunning blue water. The filling pattern changes seasonally causing the river to change its shape. The vibrant blue color comes from glacial silt.
# Glacier Waterfalls in Svalbard, NorwaySvalbard, which means cold coasts, is an archipelago in the Arctic, constituting the northernmost part of Norway as well as of Europe. It is located about 400 miles (650 km) north of mainland Europe, midway between mainland Norway and the North Pole. Despite being so close to the North Pole, Svalbard is comparatively warm, thanks to the warming effect of the Gulf Stream, which makes it habitable. In fact, Svalbard is the northernmost permanently inhabited region on the planet.
# Crystal Cave, IcelandThis cave in the glacier ice is the result of glacial mill, or Moulin where rain and melt water on the glacier surface are channeled into streams that enter the glacier at crevices. The waterfall melts a hole into the glacier while the ponded water drains towards lower elevations by forming long ice caves with an outlet at the terminus of the glacier.
# Briksdal Glacier, NorwayBriksdalsbreen or Briksdal glacier is one of the most accessible and best known arms of the Jostedalsbreen glacier. It is located in Norway and is part of Jostedalsbreen National Park. Briksdalsbreen terminates in a small glacial lake, Briksdalsbrevatnet, which lies 346 metres (1,135 ft) above sea level.
# Birthday Canyon, GreenlandBirthday Canyon, carved by meltwater, is 150 feet (45 m) deep. This photo was taken in 2008. Along the edge of the canyon, lines on the wall show the stratigraphic layers of ice and snow laid down over the years.
# Elephant-Foot Glacier, GreenlandThe Arctic Elephant-Foot Glacier found in northern Greenland. The grey zone at low elevation on the glacier is the ablation zone incised by meltwater channels, clearly separated from the white surface accumulation zone higher up. This unique glacier is located at an astonishing geographical location on the north-east coast of Greenland (81° N).
# Frozen Wave, AntarcticaThis unique frozen wave is located in Antarctica. It was discovered by american scientist Tony Travouillon in 2007. These pictures do not show a giant wave somehow snap-frozen in the very act of breaking. The formation contains blue ice, and this is compelling evidence that it was not created instantly from a wave of water.
