I've got a jar of ash from the eruption. Collected in Spokane a few days after the event. Some 260 miles ENE of the mountain. I use it as a paper weight on my desk. It's fun to shake up and watch the ash settle. I had one too. Until my son turned it into mud. |

Quote HistoryQuoted: I just read the "18 volcanoes" article. I've never been there (that I'm aware of) so does anyone know what direction that picture is taken from of Crater Lake? Here's Crater Lake Lodge. You can see the island (Wizard island) on the left so looking at the other pic it's directly across from it on the other side. You can click on the link and it will give you an idea of which side its facing. http://www.willhiteweb.com/crater_lake_national_park/crater_lake_map.jpg   |

I went there this weekend.
There are countless dry riverbeds, all filled with black, jagged rocks. |

Quote HistoryQuoted:
Two entirely different magma types. Hawaiian volcanoes expel very low viscosity, low gas content basalt lavas while those underlying Yellowstone are high viscosity, high gas content types. The longer the caldera charge cycle takes, the more gas (pressure) buildup can occur. When the magma is finally vented to the surface it'll explosively decompress and produce Plinian-style eruptions. That is, vertical ash columns, pyroclastic flows and a shit-load of tephra whose overall ejected volume is dependent on the size of the magma chamber supplying the system. In Yellowstone's case, nothing about a ring-fracturing eruption will be considered "low energy". Quote HistoryQuoted:

Now look up the Toba super-eruption...St. Helens ejected about one cubic mile of ash. Toba ejected 200 cubic miles of it. 
That's 3 times the size of the latest Yellowstone eruption. That eruption almost wiped out the human race about 75,000 years ago. |

In Yellowstone's case, nothing about a ring-fracturing eruption will be considered "low energy". It's about time you wily scientists finally found something you know with absolute certainty. Bravo! |

One of the crazy things that boogles my mind is when I read that "18 volcanoes"bis seeing the pictures of ones that erupted 1,300 and 2,000 years ago and the one 7,000 years ago!!! How there still is those white lines and that clear cut circle of ZERO life even THOUSANDS of years later!!!!! It makes you think about how fragile(NOT INSIGNIFICANT) life is

Ed eta; I used to cut a lot of wood I had several friends that sawed salvage timber in the St. Helens blast zone. They were going through 2 to 3 chains a day, each. They had to wear masks too. A lot of the timber they were cutting was old growth that had been knocked down by the blast. I was told they had to clear a 'girdle' on the logs of any bark with a hatchet first - then sweep it clean with a broom, before they fired up their saws, in an effort to remove as much of the silica as they could. They still went through that many chains. They made a ton of dough, but it sounded like a bunch of extra work. |

Quote HistoryQuoted: It's deep too. I think the deepest part is around 1900ft or so. 1943 feet and the deepest lake in the US, and 7th deepest in the world. THAT would have been an eruption to see. Not to mention the caldera collapse. I don't think there have been any notable caldera formations in modern times, but it must surely be an impressive event - especially when on the scale of what happened at Mt Mazama or Yellowstone. I think the closest we are likely to get to witnessing a collapse is going to be the much calmer events that happen in Hawaii, like this video I found hosted at WSJ from the crater floor collapse at Kilauea. |

Yea I can't imagine how spectacular it would be with 1900 ft of water suddenly collapsing onto the magma chamber. Would be a more explosive event then Mount St Helens for sure.  |
