BEIJING, Aug. 4 (Xinhua) -- A team of Chinese explorers has wrapped up a scientific expedition into Heizhugou, revealing more information about the mysterious ravine known as "China's Bermuda Triangle."
Veteran explorer Liu Yong, who led the team, said they crossed the Luosuoyida Canyon, the core area of Heizhugou in southwest China's Sichuan Province, between June 21 and 24, and have filed a preliminary report of their findings to the local government.
A habitat of giant pandas and a national nature reserve, Heizhugou has been popular on social media and among expedition enthusiasts due to the mysterious disappearance of humans and livestock there.
The expedition, backed by the local government, marked the first of its kind into the "Death Vally" of Luosuoyida, which has been off-limits to travelers despite tourist development in some other parts of Heizhugou.
At a press conference in Beijing, Liu said they encountered many unexplained events, including temporary failure of their walkie-talkies, during the adventure. At one point, his mechanical compass deflected up to 30 degrees.
Assisted by local guides, Liu's five-member team managed to trek 29 km in the core area's primeval forests. The team marked out risky areas, camping sites and water sources along the route, and took many photos of the area's fauna and flora.
Liu said the previous missing cases may be related to the local geomagnetic anomaly and other factors such as the foggy weather and lack of experience and preparation.
