On the radio, I heard that Mt St Helens is spewing ash 30,000 feet in the air. (?)So, on my drive home I looked hard, but couldn't see her - just what appeared to be clouds. I've looked on my news sites as well, but nothing.
Oh, and appreantly we had a baby earthquake today. Didn't feel that either. Sheesh!
Has anyone heard anything?

Mt St Helens exploding?
Well, CNN and FOX news aren't reporting much beyond that Mt. St. Helens is spewing ash. They couple this with views of the crater interior, where rivulets of lava can be seen.
I don't think there's much of an eruption here. We'll see what pans out tonight.
And, Anna K, if you're close to the mount, I wish you and yours well.
UPDATE: Here is the report on the current activity of Mt. St. Helens as provided by the USGS:
U.S. Geological Survey, Vancouver, Washington
University of Washington, Pacific Northwest Seismograph Network, Seattle, Washington
Mount St. Helens Information Statement,
Tuesday, March 8, 2005, 6:00 P.M. PST
A small explosive event at Mount St. Helens volcano began at approximately 5:25 p.m. PST. Pilot reports indicate that the resulting steam-and-ash plume reached an altitude of about 36,000 feet above sea level within a few minutes and drifted downwind to the east-northeast. The principal event lasted about 30 minutes with intensity gradually declining throughout. The USGS Cascades Volcano Observatory lost radio signals from three monitoring stations in the crater soon after the event started. The cause of the outage won’t be known until scientists can visit the crater tomorrow to assess the situation, weather permitting. The event followed a few hours of slightly increased earthquake activity that was noted but not interpreted as precursory activity. There were no other indications of an imminent change in activity.
The current hazard assessment for the ongoing eruption mentions the possibility of such events occurring without warning, and the assessment remains unchanged. The eruption could intensify suddenly or with little warning and produce explosions that cause hazardous conditions within several miles of the crater and farther downwind. Small lahars could suddenly descend the Toutle River if triggered by heavy rain or by interaction of hot rocks with snow and ice. These lahars pose a negligible hazard below the Sediment Retention Structure (SRS) but could pose a hazard along the river channel upstream.

Hawke, thank you.

Here is a link to Mt St Helens. http://www.fs.fed.us/gpnf/mshnvm/
Many of my friends watched her erupt. I'm so jealous! We're all curious to see what will happen next.
