One of China’s most popular tourist destinations has been hit by an avalanche in the middle of a busy holiday period. The landslide at Jade Dragon Snow Mountain in the southern province of Yunnan took place on Friday morning near Baisha Ancient Town, another popular local attraction. Although the incident happened in the middle of the extended May Day public holiday, no injuries were reported. Visitors to the area recorded dramatic pictures of the avalanche, showing clouds of dust being thrown into the air along the mountainside, footage first published in the local newspaper Spring City Evening News . The Yulong county government said rocks had been sent hurtling into the valley below, but the area was uninhabited and away from the main tourist areas and there had been no risk to life as a result. Jade Dragon Snow Mountain, also known as Mount Yulong, is the southmost glacier in the northern hemisphere, stretching over 35 kilometres (22 miles) and consisting of 13 peaks, the highest of which is at an altitude of nearly 5,600 metres. One of China’s busiest tourist sites, it attracted about 4.32 million visitors last year, up 15 per cent from a year earlier, according to the local government. A preliminary investigation by the authorities concluded that the rock collapse had been caused by a free-thaw effect in the alpine landscape, which is common in high-altitude mountains and frozen soil regions. A similar incident was recorded on the mountain in March 2004. The government said it was conducting comprehensive field inspections and had set up warning signs on the periphery of the collapsed area to stop members of the public from entering the area. The county will then call in geologists to conduct a comprehensive analysis and assessment of the impact of the incident.
