Half ridge peak

Half ridge peak

Banji peak, with an altitude of 5430 meters, longitude of 102.907519 and latitude of 31.221169, is located in the depth of bipenggou scenic spot, Lixian County, Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province. It is a golden tourist route of miyaro in Jiuzhaigou, more than 250 kilometers away from Chengdu, the capital of Sichuan Province. It takes about five to seven hours from Chengdu to the base camp. On May 4, 2004, seven climbers successfully reached the top of a mountain which was not reached. The altitude of the peak was 5430 meters. The peak is hidden behind a ridge, so there is no local name for the peak. According to the shape of the peak, the first climber named it Banji peak.

Climate conditions

The semi ridge peak area is located in the transition area from the mid subtropical monsoon climate to the continental plateau climate. Due to the plateau topography, the climate is cold in winter and cool in summer, dry all the year round, and the rainfall is rare. The annual precipitation is 1100-1600 ml. the precipitation is mainly concentrated in the rainy season (may), and the natural vertical band spectrum of the mountains is very representative. And the temperature changes violently, the four seasons are not obvious, the daily temperature difference is large, sometimes more than 20c. The annual evaporation is 1500 mm, the frost free period is 220 days, the annual average temperature is 12.2 ° C, and the annual illumination is 2214 hours

.

Banjifeng is a typical plateau climate. It is cool in the morning and evening, hot at noon, blue sky and white clouds, bright stars at night and fresh air. However, due to the high altitude, some people will have different mountain reactions.

Climbing routes

On May 4, 2004, seven climbers successfully reached the top of a mountain which was not reached. The altitude of the peak was 5430 meters. The peak is hidden behind a ridge, so there is no local name for the peak. According to the shape of the peak, the first climber named it Banji peak. In August and October of the same year, after organizing the first climb, we organized another climbing activity for the new route of the peak. The peak has formed four different routes from C2, which is really an ideal mountain to climb in the alpine way. More than 250 kilometers away from Chengdu, the capital of Sichuan Province, it takes about five to seven hours from Chengdu to the base camp

.

Right (click to enlarge): the contour map shows that the green area is the forest covered area, shanghaizi is the base camp and the end of the road, the blue line leading to C1 is the climbing route, the black dotted line of the valley is the former forest road, which has been paved into Baiyou Road; the county boundary of the ridge indicates Wolong County in the southeast corner, and the others are Lixian County. Between 5414 and 5430, there is a large area of glacier, but it is not shown according to the drawing method of glacier. The southern direction of the map is the direction of Yaofeng of Siguniang mountain, which connects yangmantai peak to Yaofeng; the ridge extends not far to the northeast, which is Dahuang peak of 5922, the second peak of Aba Prefecture.

Shanghaizi is the end of the asphalt road in bipenggou, 3500 meters above sea level. It can park nearly 100 cars of all kinds. In addition to two large color steel buildings, every May day or November day, villagers in the gully will come here to build some tents to do tourism business. Migrant workers have a lot of opportunities to earn money, so the price for back work is very high. Shanghaizi is a good place to be a base camp. There are good restaurants in the color steel buildings. You still need to set up your own tent to live in. You can build a comfortable big tent.

From the base camp, walk down the road for about 300 meters. If the weather is fine, you can clearly see the glacier near the top of the mountain on the right. Because it is too clear, you will think that it is very close and make a wrong judgment. If you find a gully, you can easily find the way up the mountain. The connection between the gully and the highway is a gentle alluvial fan. Up there is a forest path. You have to turn to the left side of the gully before you go far. Because there are no people in bipenggou, the forest path is not very obvious. Besides, it's easy to get lost in the forest of Sichuan. We must make good road signs in climbing activities. When we went up the mountain, there was no snow in the forest, but when we went down the mountain, the snow was too thick, so we had to stop many times to find our way.

After coming out of the forest, turn left. After passing a grassy slope, there is a relatively flat woodland, including a dilapidated cowshed. It is measured that the altitude here is close to 4000 meters. It is not easy to clear the flat land for a camp in the woodland. Moreover, it has only risen 500 meters from shanghaizi, so it is only an alternative for a camp. If you make a camp here, go to the right side of the ditch and climb directly along the gravel slope. It's a straight road to the glacier, but the slope is steep, about 40 degrees.

From the rocky slope on the left side of the woodland to the top, around the shrubbery dominated woodland, and then up the road, it's clear and easy to distinguish. Except for a few low shrubs, it's only stone slope and grass slope road. The 4462 small peak on the left side of the road can also be used as a reference. After a few big slopes, there will be a platform as big as a football field. We'll be in the snow. It's estimated that it's a dry sea, and it can be built for 30 years A tent above the roof. The time from the base camp to here is four to six hours. If you have poor physical strength, you can plan it in eight hours.

This is C1 (LAT: 31o15'12.5 ", long: 102o54'81.4", 4454m). In addition to using snow as drinking water, there should be several gullies flowing through in summer. We also use water bags to take water from the gullies, which can save fuel. Besides rocks and grass near C1, the elephant is just below the peak, and the upward road is also clearly visible. You need to cut a section to the right, cross a pass, and climb up the glacier.

C1 to C2 Road, if there is no snow, it will be very easy to walk. When we walk, it's snowy and we often step into the stone crevice. Before reaching the pass, the slope reaches 40 degrees, which is prone to avalanche in case of heavy snow.

The pass is not like the one between two peaks, or the concave part of a ridge. The height of the pass is 4850 meters. After arriving at the pass, the road leading to C2 is to the left along the ridge. On the right side of the ridge, which is not visible before going up the pass, is the end of the glacier. Downward, there are all rocky slopes, which should also lead to shanghaizi base camp.

Climb up along the junction of glacier and ridge, and cross several ridges to C2 (LAT: 31o14'64 ", long: 102o55'13.5", 5026m). C2 is a flat slope of about 10 degrees, which can build dozens of tents. After leveling, you can make camp. Our camp is 4980 meters away from the wind, but we can only build two or three tents. C1 to C2 take about five or six hours to climb.

From the contour map, above C2 is a circular route, because the weather was bad on the day of climbing, and the slope of the glacier we had to pass was about 50 degrees. In order to avoid forced climbing leading to avalanche, we still walked at the junction of the rock ridges of the glacier, which is equivalent to the mixed shape of snow and rock. It is a clockwise direction of the circular route, which is more difficult. The steepest point is 70 or 80 degrees.

At that time, we wanted to climb up from a snow ditch, but the snow ditch was too steep and there was the danger of avalanche. We had to take the rock ridge. The rock ridge was divided into four rope sections. The ice and snow route was protected by rocks. After these four rope segments, there is a gentle ridge leading to the peak. On the right side of the ridge, we have three more rope segments to reach the peak.

In fact, there is a very long snow ridge at the top (summit, lat: 31o14'41.1 ", long: 102o55'39", 5430m). In the northwest of the snow ridge, there is a gentle snow slope, in the southeast, there is a snow eaves, and in the southeast, there is a ridge, which is connected by a stone peak.
