"Giant Ice Wall" Forms on China-Russia Border Lake


A giant ice wall extending more than a dozen kilometers has risen on Xingkai Lake, a border lake between China and Russia. Standing around 20 meters high, the wall in northeast China's Heilongjiang Province is made of chunks of ice, piled up by strong winds. Xu Zhong, head of the meteorological station at Xingkai Lake, said the phenomenon is rarely seen as it needs lasting low temperatures, strong winds, water flow under the lake surface and ice chunks to form.
