With all the cloud cover, and the mountain sticking out through one of the only holes in the clouds, we probably got a better view than those at Johnston Ridge.

VANCOUVER, Wash. - Mount St. Helens shot a steam and ash plume at least 16,000 feet into the air Monday after a large rockfall from the lava dome in the volcano's crater, scientists said.
Pilots reported the plume rose between 16,000 and 20,000 feet in the air, scientists at the Cascades Volcano Observatory said.
The rockfall coincided with a magnitude 3.1 earthquake shortly after 9 a.m. Monday at the mountain, scientists said. Such events are expected during growth of the lava dome, they said.
"There is no evidence of an explosion associated with this event," the observatory said in a statement.
Clouds obscured the crater at the time.
"We don't know how much steam and how much ash," Cynthia Gardner, scientist in charge at the observatory, told The Columbian. "These are very short-lived events."
Lava has continued to push into the crater — most recently forming a sheer rock fin — since the 8,364-foot mountain reawakened with a drumfire of low-level seismic activity in September 2004.
The crater was formed by the volcano's deadly May 18, 1980, eruption that killed 57 people and blasted about 1,300 feet off the then-9,677-foot peak.

Or just don't live.
No, Bush's fault is located more towards the center of the nation. ;-)

Heh...
Is there a volcano behind us or are you just happy to see me?
Heh... That's my husband and me on one of our trips up there... Volcanic display courtesy of Photoshop, of course :~D

.Somebody is going to lose a trailer.
Great photos! Thanks for sharing.
That fin is growing at 3-4 feet a day according to some sources. I guess she has a right to get steamed. To push that fin up that far, I would think she is building a lot of pressure. Good thing that the act of pushing up the fin might release some of it.
Impressive photos, HOTD!
See posts 17 and 24.
LOL
I have seen that view many times enroute from SEA to LAS. Sometimes the pilots will point St. Helens out and sometimes not. I am surprised that with it blowing off steam that you weren't routed further east 'just in case'.
a comfortable distance :-)
Who gets the trailer when the Klintoons finally split up? LOL!
BUMP!
I lived in CA at the time she blew. I worked for a ceramics company and I remember the boss driving northwest and coming back with buckets and buckets of ash.
It made the most BEAUTIFUL blue glaze I'd ever seen. I have a piece of pottery glazed with Mount St. Helens ash.
I would love to see a pic of the pottery....
LOL!!!
