    Arlington / Oso / Darrington Slide

    For those who venture out beyond Starbucks, you will be quite familiar with riding in this area where this massive slide has happened.

    If you can envision the hillside surrounding Oso / Arlington collapsing down on the residents, that's pretty much what you've got by the sounds of it.

    Anyone who rides for pleasure in Wa has been around that area a pile of times... it will be sad to see the results the next time through.

    Oso is the town the the tiny little "loop road"... it's on the backside of Lake Cavanaugh... on Arlington Darrington highway.

    The highway itself is completely buried and non existant at this point.

    Sad news, indeed.


    Every time I've ridden through there, I've marvelled at how extensvely the surrounding hills and mountains have all been totally clear-cut at some point, the original forests having been totally razed in the name of construction/development of North America's great wild west (and profit).

    I wondered, after hearing about the slide, whether the logging practises in the area might have had any influence on the stability of the grounds there, and if and when questions about it might arise through the mainstream media.

    After looking at the photos of the slide propagation zone, it appears to me that the slide started in an old re-planted cut-block, lending some credence to the possibility of the idea holding merit.

    Nothing in the news about it yet.

    It is well known that clear cut logging causes mudslides. They enacted regulations up here many years ago to prevent clear cut logging if the slope is too great.
    There are a lot of towns in this same position. Built right under a mountain or in a valley. Too many to count.

    On the news they were talking to some guy in geology, who pointed out there's quite a few areas around here where just such a slide is an almost certainty. He mentioned the entire stretch of Chilliwack Lake Road has the perfect conditions for this to happen, including the entire community of Slesse Park, the immediate area has 100's of homes. He said Hwy 1 around Boston Bar is also at risk, as well as areas in North Van through to Lions Bay.

    Don't want to sound like an "I told you so", but the 3 homes I've bought since 18 yrs old, I've studied the lay of the land, always lived in a high flat area. I remember my baby sis lived on a ranch near the top of Sumas Mtn. I was not a family favourite when I said it was a bad place to live. 9 yrs later when a land slide basically turned their back yard into an 80' cliff edge 6' from their house, I did not have to say I told you so. Anyone who lives in a flood plain, a mtn top, a cliff edge, or at the bottom of a cliff, you really are asking for issues.

    oops - apparently in 1999 a scientist did a study about exactly that spot (from the Washington Post):


    “I knew it would fail catastrophically in a large magnitude event,” though not when it would happen, said Daniel Miller, a geomorphologist who was hired by the U.S. Army Corps of Engineers to do the study. “I was not surprised.”

    and then:

    Snohomish County officials and authorities in the devastated village of Oso said that they were not aware of the study but that residents and town officials knew the risks of living in the area.

    In fact, the area has long been known as the “Hazel Landslide” because of landslides over the past half-century. The last severe one before Saturday’s disaster was in 2006.

    “A slide of this magnitude is very difficult to predict,” county Public Works Director Steve Thomsen told the Seattle Times, which first reported on Miller’s analysis. “There was no indication, no indication at all.”

    No landslide warnings for the area were issued before the disaster, which came after weeks of heavy rain. The rushing wall of quicksand-like mud, trees and other debris flattened about two dozen homes and critically injured several people.

    So I wonder if land prices relfected this fact, did everybody get their homes cheap? Nothing to be said for injuries/lost life but if people are upset about the loss of their property...

    I'm still amazed when I see this on the news. I've ridden that little loop road a few times for fun. I don't think it's even there now.

    People build and live where they want.
    I live in a Flood plain, I know the risks and I accept them.

    The West coast is built over earthquake prone faults, Doesn't stop people living there.

    If we ran away from all dangerous areas, the Pacific rim countries would be deserted.,

    True enough. But a flood won't squish you like a bug, or bake you under 40' of super heated ash.

    Ya - and living directly beneath a slide-prone slope that had been virtually guaranteed to let go some time soon by engineer specialists ... well ...

    May as well build on the rim of a steaming volcano vent.

    My inital post was a comment on the inherent destabilization that strip-logging causes to slopes, and how extensively that area has been logged over the recent decades. Some dangers are natural and unavoidable, and some are exacerbated by humankind's insatiable appetite for profit, space, and resources.

    I know the road you mean, but based on a map I saw in a news article the slide looks to be east of the eastern end of the road..

    I have done 530 a few times through Oso, but none of the smaller loop roads in the area. Very sad to see so close to home.
