Massive lava ‘fin’ rises up in Mount St. Helen’s crater

060503helens_slab_422.jpgA spectacular new structure has formed inside the crater at Mount St. Helens, just in time for this weekend's opening of the Spirit Lake Highway.A slab of rock the size of a football field is standing on end inside the crater.

The giant 'fin' is pushing upwards of four to five feet a day, but is not growing taller because it tends to crumble as it grows. - more on katu
