Glaciers are formed by years of snow, which is compressed, re-approached and re-frozen into ice. Glaciers have certain levels and forms. Under the action of gravity and pressure, glacier itself will move on the one hand, and on the other hand, in the process of glacier movement, it will produce external forces such as erosion, transportation, deposition and so on on the ground surface. Glaciation is an important form of external force.
Due to the death of New Zealand is located in the plate boundary, due to the collision of the Pacific plate and the Indian Ocean plate extrusion effect, the earth’s crust uplift, makes the New Zealand is given priority to with mountainous, hilly terrain, especially in New Zealand’s south island more steep terrain, which is located in the south island of mount cook is the highest mountain in New Zealand, altitude 3754 meters, the glacier near the top of the mountain there is a lot of distribution.
Mount cook is located in the south Alps, which runs from northeast to southwest and runs through the south island of New Zealand. Mount cook is located in the central part of the mountains and stretches for hundreds of kilometers. It is located between latitude 42° and 44° south. The tasman glacier snakes down from the top of mount cook, measuring more than 28km in length and about 4km in width. It can be up to 600m thick and more than 3,000m above sea level.
Due to gravity, tasman glacier slowly slide to the low altitude, a day of sliding speed is about 23 to 45 cm, in the process of ice slide down, on the surface for the plane at the bottom of the glacier erosion, at the same time on the surface of the glacier formed numerous cracks and ice tower, the modelling is various, glittered in the sun, with a beautiful view.
The tasman glacier is a famous mountaineering site in New Zealand, with relatively complete supporting facilities, but it is still one of the most dangerous high mountain areas in New Zealand. The tasman saddle is the core of the entire tasman glacier, surrounded by high and precipitous snow-capped mountains and glaciers, and the ice-covered ground is filled with crevasses of varying sizes. In the tasman saddle, there are two important mountain huts, tasman saddle huts and Coleman huts, built especially for climbers, which provide the most effective protection for safely climbing and exploring the tasman glacier.
The best way to see tasman glacier is to take a cruise ship. When you travel through icebergs of large or small size, it is like entering the world of ice and snow. You not only experience the grandeur of the glacier, but also feel like entering a romantic fairy tale world.
