SEATTLE, Washington (AP) -- If the skies are clear as forecast, volcano watchers who turn out for the reopening of the Johnston Ridge Observatory on Friday will get a spectacular view of a hulking slab of rock that's rapidly growing in Mount St. Helens' crater.Remember when we used to teach that everything significant in nature took millions and millions of years because it moved so slowly? That was awesome...
It's jutting up from one of seven lobes of fresh volcanic rock that have been pushing their way through the surface of the crater since October 2004.
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.
