Poof!

St. Helens burped off a huge steam/ash cloud minutes ago. Live webcam shot here, if you can get through: http://www.fs.fed.us/gpnf/volcanocams/msh/

Nobody knows what it is really. Saying "steam and ash plume" and "alerting pilots within 150 miles." Safe here, but fun to watch. This pic is from about 10 minutes ago, from Johnson Ridge:
