YUXI, YUNNAN: Ten divers began a seven-day search for a possible underwater 
"Atlantis" on Friday in the Fuxian Lake near Kunming, the second-deepest 
freshwater pool in the country. 
Local diver Geng Wei first told of a large ancient city in the lake eight 
years ago, thought to span 2.4 square kilometres. Geng claimed to have seen lots 
of square boulders more than 1.4 square metres in size, either piled or 
scattered deep underwater.
In 2001, the local government launched the first large exploration of the 
lake, which was broadcast live across the nation by China Central Television 
(CCTV). 
A submarine was sent down and detected a 60-metre-long stone wall. Divers 
unearthed a shard of pottery embedded in the stone wall, which was found to date 
back to the Han Dynasty (104 BC-220 AD).
The evidence convinced Chinese archaeologists that there might be some 
constructions under the lake, possibly more than 1,800 years old.
This hypothesis was substantiated on Friday in the first dive, when Geng was 
videotaped finding three notches, each 1.2 metres long and 45 centimetres wide, 
on a moss-covered square slate. 
The "IY"-shaped notches must have been artificial, and "support the idea that 
all the stones were once processed by humans," said Li Kunsheng, director of the 
Archaeology Research Centre of Yunnan University. 
But Liu Qingzhu, director of the Institute of Archaeology under the Chinese 
Academy of Social Sciences, added: "We still have not enough information to 
verify that these slates made up a city. Even the shard and shell cannot 
represent the exact date of the rocks."
After Geng announced his discovery eight years ago, more claims were made of 
underwater finds in the lake, which boasts a water surface of 212 square 
kilometres and an average depth of 87 metres. They include a slate path, an 
arena-like building and a small pyramid.
However, Liu, who was present during two underwater excavations, said no 
pictures or evidence about the above "findings" had ever been provided by these 
people.
Despite this, experts have engaged in a prolonged debate over whether these 
slates are relics of a documented city that mysteriously disappeared.
The history books show that the city of Yuyuan to the north of the Fuxian 
Lake once existed, but it disappeared from records after the Southern and 
Northern Dynasties (AD 420-589). 
Li said the lake is situated on an earthquake-intense belt, which might 
suggest that the underwater construction may have sunken in rising waves during 
a quake.
Dissenters argue that the stone structure is contrary to buildings of this 
era, which were made of bamboo, wood or mud. 
Liu said that while all the answers to this underwater mystery will not be 
found in seven days, "we'll try to outline a layout map of what is beneath, and 
do more in the future."
