Mount St. Helens Pregnant Crater!

I don't know about you, but Mount St. Helens has always fascinated me! Here is an update on a potentially explosive situation.





Massive Rock Slab Growing at Mount St. Helens Crater

If the skies are clear as forecast, volcano watchers who turn out for the reopening of the Johnston Ridge Observatory on Friday will get a spectacular view of a hulking slab of rock that's rapidly growing in Mount St. Helens' crater.

It's jutting up from one of seven lobes of fresh volcanic rock that have been pushing their way through the surface of the crater since October 2004.

The fin-shaped mass is about 300 feet tall and growing 4 feet to 5 feet a day, though it occasionally loses height from rockfalls off its tip, said Dan Dzurisin, a geologist at the U.S. Geological Survey.

It began growing last November, steadily moving west and pushing rock and other debris out of its way as it goes.

Mount St. Helens has been quietly erupting since a flurry of tiny earthquakes began in late September 2004. Scientists initially mistook the quakes as rainwater seeping into the hot interior of the older lava dome.

And I'll give you the tour! The Little and I have been to Mt. St. Helens several times...she's incredible, as is Mt. Rainier (which is actually a dormant volcano as well).
