    @Phred,

    I referenced GoogleEarth re the visitors center. Apparently no new imagery between February and now. ;-)
    The DNews photo's showed earthen berms blocking roads and such, so I gathered they knew it was coming some time.
    Smart they have a mobile visitor center.

    Could that slag pile have hit Copperton or some of the homes nearby if it had come down on the eastern slope? The way it moved into the pit it appears it could have traveled some distance. Maybe they dodged a bigger bullet. Glad no one was injured!!!

    I will be interested in the investigation as to what caused the slide. When miners used trains and tracks an open pit mine could not have the near vertical walls used in today's open pit mining. My guess is that mining engineers will learn from this event.

    The gold bubble literally collapsed.

    I sure wish we (readers) could expand the pictures in your photo gallery to FULL-screen, rather than how you (DNews) have formatted it to only fill about 1/6 of the center of the screen! WHY do you guys do it that crazy way??

    Still small potatoes compared to the 1964 Anchorage / Seward landslides.

    @LDSareChristians,
    That's true. The visitors center was modular and it and the gift shop were trucked off to a remote location back in February when they first noted movement. Their April 1st press release said they were looking forward to reopening in 2014. That may be a bit optimistic at this point.

    It seems commendable the way Kennecott has handled the situation so far. I would like to see something about how this might affect the Utah economy and the fate of Kennecott workers.

    Half a *BILLION* tons of earth came down?!?!!!

    Un--REAL!!!!

    DANG!!!

    It's too bad this slide didn't occur during *daylight* hours, when they could have filmed it as it happened!!

    That would have been AMAZING to see, plus I'd think that would be invaluable to scientists and engineers to watch, analyze and learn from.

    In-con-theiv-uble!!! 8^)

    The visitors center is gone!

    If that estimate proves to be valid it would be about 3 times the volume of the 1983 Thistle mudslide and a whole lot faster.

    A better comparison would be the 1959 Hebgen Lake Earthquake. If you have ever stood on the debris pile at the visitors center at Quake Lake on the Madison River and marveled at the magnitude of that rock pile, this one is about 6 times that volume!

    Should make for an interesting field trip next year when they reopen the visitors center.

    Yikes! That is not ore? That's a massive clean-up.
