Ice can be unexpectably various…
5. Frozen Waterfalls
The growth of a frozen waterfall can proceed only gradually, for progressive freezing of the flowing water. There are thousands of frozen falls around the world. The one located at Beijing’s Myun County attracts tourists from all over the country as well as internationally. A beautiful display of nature’s art at work.
4. Ice Caves
Ice caves are a type of natural cave that contain significant amounts of ice. At least a portion of the cave must have a temperature below 0 °C (32 °F) all year round, and water must have traveled into the cave’s cold zone. There are many ice caves throughout the world, but the Eisriesenwelt Ice Caves in Austria are some of the largest known to man.
3. Ice Circles
A rare phenomenon usually only seen in extremely cold countries, scientists generally accept that Ice Circles are formed when surface ice gathers in the center of a body of water rather than the edges. A slow moving river current can create a slow turning eddy, which rotates, forming an ice disc. Very slowly the edges are ground down until a gap is formed between the eddy and the surrounding ice. These ice circles have been seen with diameters of over 500 feet and can also at times be found in clusters and groups at different sizes. (Photo by Brook Tyler)
2. Ice Spikes
These amazing ice spikes, generally known as penitentes due to their resemblance to processions of white-hooded monks, can be found on mountain glaciers and vary in size. As this accelerates, deep troughs are formed, leaving peaks of ice standing between them. Chile is home to the rugged mountain terrain of the Andes, and the severe weather extremes at different altitudes make for some stunning ice formations, like daggers looking ice field.
1. Ice Shelves
Ice takes on all sorts of interesting asymmetrical and geometric shapes, from the icy platelets above to the incredible parallel ice shelves of the Arctic. Ellesmere Island is famous for its ice shelves, but unfortunately they are diminishing rapidly in the face of global warming. Climate change caused alarming losses in summer of 2008, and scientists are concerned that this special ecosystem may soon be lost forever.
