An anonymous reader writes to mention a CNN article about the huge geological formation growing in Mount St. Helens' crater. From the article: "The fin-shaped mass is about 300 feet tall and growing 4 feet to 5 feet a day, said Dan Dzurisin, a geologist at the U.S. Geological Survey. The rock in the crater began growing last November, steadily moving west and pushing rock and other debris out of its way as it goes." Scientists think the mountain will eventually replace the lave dome blown out by the original 1980 eruption.
