From the Earth Observatory website:

NASA’s Landsat 5 satellite captured this true-color image of Redoubt Volcano and its immediate surroundings on March 26, 2009. Against the backdrop of a snowy landscape, the volcano’s steam plume must be found by its texture rather than its color. Above the volcano summit, the vapor billows like giant balls of cotton. On either side of the steam plume, brown volcanic ash appears. Although some of the ash is probably airborne (a large swath of airborne ash appears in a wider view of the area acquired on the same day), some of the ash has settled on the ground. Settled ash is especially apparent east of the plume, where small ridges appear surrounded by darker ash. North of the volcano summit, the lahar appears nearly black, narrowing into the Drift River Valley.

I feel very sorry for the people who lost their homes
