On a Space Station expedition, astronauts observed and captured this detailed image of the volcano's summit caldera. In the center of the crater sits a lava dome that is 876 feet above the crater floor and is about 3,500 feet in diameter. The dome began to form after the May 18, 1980 eruption of Mount Saint Helens . After the eruption, there was not any dome building eruptions for more than a decade. Afternoon lighting accents the flow features in the volcanic and debris flows and the steep valleys eroded into the loosely consolidated material near the summit. This picture was taken on October 25, 2002
