A soldier on a bridge over the Fujiang River prepares to destroy floating objects obstructing water draining from the Tangjiashan "quake lake" in Mianyang, Sichuan Province June 10, 2008. Floodwaters crashed out of the dangerously unstable "quake lake" in southwest China on Tuesday after soldiers blasted open a sluice, significantly easing the threat of disaster for hundreds of thousands of people downstream.
