Pacific Northwest mountaineers always talk about our volcanos and the possibility of another eruption. Most of the time, Mt. Rainier is the focus.  Over the past few weeks, the most heavily instrumented volcano in the world - St. Helens - started to wake up.

It finally erupted today.  While a bit of steam and ash is not nearly as dramatic as the explosion in the 1980s, it is still really interesting to watch.
