Pretty awesome! (unless you are in the plume, of course.):
The dust plumes in this astronaut photograph stretch more than 120 kilometers (74 miles). The vigor of the winds also can be judged from the fact that they are lifting dust particles from the valley floor to more than 1200 meters over the mountains. The winds channel the dust through a low point in the mountains, about 800 meters lower than the ridge crests to north and south (image right).
