A bulldozer clears snow on a provincial highway at Barkol Kazak Autonomous county in Hami, northwest China's Xinjiang Uygur Autonomous Region, early March 9, 2013. A snowstorm hit Barkol late Friday, forming two-meter-high snow walls at several sections of provincial highways S303 and S238 which disrupted the traffic. Rescuers from local police and highway maintenance department had to work 14 hours to evacuate some ten trapped vehicles and 50 people. [Xinhua/Zhang Jiangang]
