This is really amazing…Four to five feet per day?! I would try to avoid that area for a while.

SEATTLE — Visitors to the Johnston Ridge Observatory at the Mount St. Helens National Volcanic Monument can look forward to a spectacular view of a hulking slab of rock that’s rapidly growing in the volcano’s 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, said Dan Dzurisin, a geologist at the U.S. Geological Survey.
