The fin takes a hit - Mount St Helens update

The large outburst from Mount St Helens on Saturday night was definetely caused by a section of the "fin" breaking away.

The images below were recorded by the USGS remote camera at the Sugar Bowl - the before and after shots clearly show a large section the rock structure had fallen. More images are available at the USGS/Cascades Volcano Observatory. (Click on the image to enlarge it and see the animation.)
