New Zealand in three glacier experts teach you how to play.

The earth's glaciers are rapidly reduced, the glacier will also become more and more rare forms of tourism. However, tourism, in addition to the front of the glacier to enjoy a treat, but also how to play? The three New Zealand glacier -- Fox Glacier, Franz Joseph glacier, Taziman glacier -- provides us with abundant answer: hiking, climbing, canoeing, even by helicopter, try by hook to look for sth. in the professional guide, 360 degrees to explor glacier panoramic details, a different perspective, the senses will be fully mobilized, is no longer monotonous boring "see spots". What is more, the Fox Glacier and Franz Joseph glacier because from the beginning of 1984, growth period, every day has increased by about 0.7 meters range, flow rate is generally 10 times the glacier, better known as the most "speed" glacier. New Zealand tourism project development department for ecological attention, also makes it a glacier tour full of meaning.

The three New Zealand glacier.

The glacier colors: blue and white glacier is not one, but a hue, saturation and levels of change, knowledgeable people by its color to identify the ice age and morphology. Ice is only the shorter wavelengths of light scattering sunlight (i.e., blue), so, blue light kept scattering and reflection in the glacier, to form the most common blue; with the increase of pressure, hardness, the gaps are reduced and densification disappear constantly upgrading, glacier blue deeper, and in the glacier, the reflection of sun light is relatively poor, the glacier became emerald, in a hidden place, found in emerald. In addition, the color can identify glacier hierarchy depth, deep cracks usually is white, blue gradually, until the deep place into a dark green and black.

Look at the glacier year: Earth has at least 3 glacial period, namely the Precambrian period (600000000 years ago), Carboniferous and Permian (2-3 million years ago) and the Quaternary period (2000000 years ago). Glaciers are like a tree rings, which is composed of layers of snow and snow in summer, due to thawing, and the surrounding dust environment, the glacier surface will form a deposition pollution annual layer, for example, New Zealand Cook National Park in the Tas Mani glacier block on ring is the formation of the local volcano eruption the dust. Before doing homework, visitors can also according to the natural layer calculated glacial age.

The glacier shape: Glacier modelling is undoubtedly the most attractive, the senior game player especially good shooting all kinds of glacier ice shape. The main shapes are: half a bowl of U-shaped cirque, horn peaks, sharp knife ridge, steep cut spur, U Valley, V Valley, the fjord (U Valley Beach), hanging (U Valley to form the main glacier and glacial cross the gap, which is now the many falls the boulder), etc..
