An impressive scene from Afghanistan

Described as a "mudslide" at the original LiveLeak site, and accompanied there by an incredible number of inane comments, it is nevertheless a video that has to impress the viewer with the incredible power of natural forces.

Some of the boulders carried by this flash flood/avalanche appear to have the weight of a small vehicle, and the erosive power of the process must be incredible. It's no surprise that roads and bridges are difficult to maintain in bare mountainous landscapes.
