Transparent Mengke Glacier (Provided by Changhe Changhe)
The Qilian Mountains, which extends over 2,000 kilometers into Qinghai, is the northern edge of the Qinghai-Tibet Plateau. In the ancient Xiongnu language, Qilian means "Heaven." Qilian Mountain is named after the "Tianshan Mountain," and because it is located south of the Hexi Corridor, it is also called Nanshan Mountain. The mountains border the Altun Mountains in the west, Xinglong Mountain in Lanzhou in the east, Qaidam Basin in the south and Qinghai Lake in the south. The Qilian Mountains range from northwest to southeast and consist of several parallel mountains. The glaciers bred in Qilian Mountains have deep roots in the Silk Road. In the Hexi Corridor, which is a typical continental arid and desert climate, glaciers in the Qilian Mountains irrigated the oasis and became the lifeblood of their economic development and people’s lives.
Daxue Mountain, located in the Subei Mongolian Autonomous County of Gansu Province, is a complete hill area formed by the interruption of Qilian Mountains. The north is the Changma Basin, the East Sulie River Gorge, the south is the Yema Valley, and the west is the Gongchu Dashan Hankou. It is 88 kilometers long, 20 to 30 kilometers wide, and the mountainous area is about 2,200 square kilometers. Daxueshan Mountain has an average elevation of 4,000 meters and the highest peak is 5483 meters. It is the highest mountain on the northern tip of Qilian Mountains. Due to its location in the northwest, Daxue Mountain is rich in precipitation.
Daxueshan has 203 glaciers with an area of ​​159.3 square kilometers. There are 44 glaciers in the Tiger Valley area of ​​Daxue Mountain, covering an area of ​​54.3 square kilometers. The No. 12 glaciers in the Tiger Valley, also known as the “Transparent Dreams†glaciers, were discovered by experts from the Alpine Glacier Research Station of the Chinese Academy of Sciences in 1959. “Transparent Dream Ke†is a Mongolian language that means a tall and broad Daxue Mountain. The glacier is 10.1 kilometers long and has an area of ​​21.9 square kilometers. It is the largest valley glacier in the Qilian Mountains and belongs to the polar continental glacier with double valleys. It has a large snow accumulation area. The end of the glacier is 4,260 meters above sea level, and the highest peak is 5,483 meters above sea level. The glaciers have a gentle slope. The maximum slope in the snow area is 26 degrees and there is no avalanche hazard. Its great capacity and high safety are its distinguishing features. Has the characteristics of stable glaciers.
Into the mountain route:
From the Yumen town chartered vehicle to the Tiger Gully in the northwestern direction of the main peak, the driving distance is about 130 kilometers, and the last 20 kilometers is the riverbank route, which requires that the vehicles entering the mountain have better off-road functions. There is an abandoned glacier observatory at the end of the tiger's ditch. The station near the observation station is an ideal base camp BC location with an altitude of 4000 meters. The straight-line distance from the BC to the main peak is approximately 10 kilometers, and C1 camps need to be established during the climb. It is estimated that from BC along the river valley, the position of the ice tongue of the No. 12 glaciers can be quickly reached, and along the gentle main body of glaciers, it is estimated that it is possible to find a better C1 campsite at a platform of about 5,000 meters of saddle; Relatively steep, the main peak is basically south of C1.
Climate conditions:
The Daxueshan area is surrounded by ice and snow, and the cold weathering and debris flow are very strong, resulting in steep hill slopes protruding from the base rock of the top ridge, generally 35-40 degrees.
The region's climate is plateau desert or semi-desert climate and alpine chilly climate, dry cold is the universal climate type, the region is located in the westerly zone, and the westerly winds prevail throughout the year. In the autumn, when the high-altitude low-pressure trough is controlled to become the alternating period of high-pressure trough, the temperature drops sharply and the air is stable. The northwesterly wind and the southwesterly wind overlap, the weather changes little, the winds are large, and the climate is abnormally dry.
The weather of Daxueshan Mountain is determined by the local atmospheric circulation and the features of the mountain terrain. Thus, the daily weather and climate changes are particularly noticeable. In winter and summer, the weather is clear and wet, and it is cloudy in summer. In winter, there are few clouds and the weather is fine. During the day, the weather is bad, and there are many blue sky at night. The wind is usually the smallest before and after the evening, and the temperature is also warmer than before and after.
In terms of weather changes, it is a unit of cycle weather. If there are clouds around the mountain, the clouds over Daisetsuzan are often the thickest and densest. If the surrounding weather is bad, Daxue Mountain is often the worst weather in bad weather. This is because big glaciers contribute to water vapor.
In recent years, the weather is generally unstable and the precipitation is high. The articles carried are ready for waterproof work and warm and windproof. According to data provided by the Jiuquan Meteorological Bureau in 2003, the total rainfall during the main flood season will be 2-3% more than in the same period of the year, including 110-120mm in Subei, and the monthly precipitation trend is less in June and more in July and August. In September, the precipitation was less, but the temporal and spatial distribution of precipitation was very uneven. The high temperatures in June-August were high in June and July, slightly higher in August, and slightly lower in September.
Transparent Mengke Glacier:
Daxue Mountain, located in the Subei Mongolian Autonomous County of Gansu Province, is a complete hill area formed by the interruption of Qilian Mountains. The north is the Changma Basin, the East Sulie River Gorge, the south is the Yema Valley, and the west is the Gongchu Dashan Hankou. It is 88 kilometers long, 20 to 30 kilometers wide, and the mountainous area is about 2,200 square kilometers. Daxueshan has an average elevation of 4,000 meters and the highest peak of 5,555 meters. It is the highest mountain on the northern tip of Qilian Mountain. Due to its location in the northwest, the Daxue Mountain is rich in rainfall. Daxueshan has 203 glaciers with an area of ​​159.3 square kilometers. There are 44 glaciers in the Tiger Valley area of ​​Daxue Mountain, covering an area of ​​54.3 square kilometers. The glacier No. 12 in Tiger Valley is 10.1 kilometers long and has an area of ​​21.9 square kilometers. It is the largest valley glacier in the Qilian Mountains.
The 12th Glacier, also known as the “Transparent Dreamco†Glacier, was discovered in 1959 by experts from the Alpine Glacier Research Station of the Chinese Academy of Sciences. “Transparent Dream Ke†is a Mongolian language that means a tall and broad Daxue Mountain. The transparent Mengke Glacier in the tiger's ditch on the northern slope of Daxueshan Mountain in the Qilian Mountains belongs to an extremely continental double-glacier glacier with a large snow accumulation area. The end of the glacier is 4,260 meters above sea level, and the highest peak is 5,483 meters above sea level. Here, the snow peaks linger all year long and go straight into the sky; The glaciers have a gentle slope. The maximum slope in the snow area is 26 degrees and there is no avalanche hazard. Its great capacity and high safety are its distinguishing features. Has the characteristics of stable glaciers.
The transparent Mengke Glacier is larger in size and has rich and varied ice scenes. The steep snowy peaks, the criss-cross ice valleys, the fantastic ice caves, the steep and steep ice walls, the ice cascades like the Milky Way, and the ice valleys Specific glacial features such as ice mushrooms, ice buckets, ice falls, and ice cracks can be seen everywhere. All kinds of landscapes are vivid. Glacier on both sides of the glacier, snow. Traveling upwards, the majestic, magnificent glaciers are at their feet, and the vast snowfields are at a glance. The majestic, majestic, and magnificent are the characteristics of the Xuemeng Glacier in the Daxueshan Tiger Valley.
The transparent Mengke Glacier holds the secret in scale and it is the largest polar continental valley glacier to be developed in Northwest China. The country has developed the "7-1" glacier in Jiaxing Pass, Gansu (with an area of ​​2.78 square kilometers), the "No.1" glacier in Xinjiang Urumqi (1.884 square kilometers in area), and the "Yihao" glacier in the Yulong Snow Mountain in Yunnan (area 1). 52 square kilometers, the area is only one-tenth of the transparent Mengke Glacier. The snow-covered fields so transparent and clean and smooth are also beyond the above-mentioned glaciers. Secondly, the transparent Mengke Glacier has a gentle relief, with the ice slope falling from 3 degrees to 6 degrees, and personnel can easily enter and climb. Thirdly, the transparent Mengke Glacier belongs to the extremely continental valley glaciers with a large snow accumulation area. The glaciers' temperature is as low as minus 8 degrees Celsius, showing the characteristics of stable glaciers. According to expert scientific surveys, the transparent Mengke Glacier receded less than 1 meter per year. Even assuming that the glacier retreat continues, it will not degrade its vitality and magnificent image and tourism value in terms of glacier retreat speed for another 200 years.
