    re. Currie.....they're watching and have done an assessment on the very real risks there in the past couple years

    Stuck up hi-res pictures of the Joffre Slide here in a timeline. When I get some more aerial pictures from Maximus I'll update

    Thx Lee! we appreciate it! Very interesting to see all the images in one place. Central looks like it might just still go, but the risks are high.

    After the first Joffre slide. Before and after.

    Pic 1 - rock avalanche trimline extends upwards into trees of Pascall's S face and deep down valley. Pic by MOT technicians.

    Pic 2 - Feb 2013 Sharon on her little birthday ski gutting the pow of Joffre's North glacier with vantage point showing the area that will be in the kill zone of the 2019 slide

    It may go all the way to the FSR but it will be big boulders with random trees so will need some amount of snow coverage

    Anyone calculated just how many cubic meters slid?

    Not sure about cubic meters, but it was approximately 2.5 million ranges.

    This was in LeeLau's article: Per Drew – “ the failure area was about 25,000 – 30,000 m², based on a failure geometry of a block approximately 200 m high and 150 m wide. The runout distance was about 4.2 km. “

    Hey, thanks for putting this together. I was about to link Brayshaw's mspaint from twitter on here before I saw you included it. That said here's a different tweet anyway because he's probably a guy worth following - hopefully he'll have more to say on it - and more specifically because I'm waaay out of my depth and I wish I knew more what he meant by this: https://twitter.com/DrewBrayshaw/sta...66185549344768

    Drew meant that last explanation re "dipping joints" in an analogy to road cuts and slumping culverts extending to adjoining masses iirc.

    Holy faaaak...the mountain just keeps falling apart...as seen from a few Steve Jones pics on facebook, another chunk just below the summit fell off. Drew a red line of what i'm guessing is the crown of the freshly cleaved chunk +/-? What's next, is the poor thing gonna get truly decapitated?

    I think its still there - just a different perspective on the shots?

    That video is some straight raw mountain action. God that gets me so hot seeing boulders smash into each other like that.

    So is that steamy, boulder-on-boulder action geology porn, or geography porn?

    Joffre is rumbling again today. These photos were captured today, June 02, 2:51pm. Photos taken by Bob van Beers, images from Facebook Group: South Coast Touring:

    It looks like the best estimate is 2-3 million cubic meters in each of the two slides.

    https://blogs.agu.org/landslideblog/...-landslides-2/

    There's a detailed analysis here, haven't looked for a PDF copy
    https://link.springer.com/article/10...46-019-01332-2

    Two catastrophic landslides occurred in quick succession on 13 and 16 May 2019, from the north face of Joffre Peak, Cerise Creek, southern Coast Mountains, British Columbia. With headscarps at 2560 m and 2690 m elevation, both began as rock avalanches, rapidly transforming into debris flows along middle Cerise Creek, and finally into debris floods affecting the fan. Beyond the fan margin, a flood surge on Cayoosh Creek reached bankfull and attenuated rapidly downstream; only fine sediment reached Duffey Lake. The toe of the main debris flow deposit reached 4 km from the headscarp, with a travel angle of 0.28, while the debris flood phase reached the fan margin 5.9 km downstream, with a travel angle of 0.22. Photogrammetry indicates the source volume of each event is 2–3 Mm3, with combined volume of 5 Mm3. Lidar differencing, used to assess deposit volume, yielded a similar total result, although error in the depth estimate introduced large volume error masking the expected increase due to dilation and entrainment. The average velocity of the rock avalanche-debris flow phases, from seismic analysis, was ~ 25–30 m/s, and the velocity of the 16 May debris flood on the upper fan, from super-elevation and boulder sizes, was 5–10 m/s. The volume of debris deposited on the fan was ~ 104 m3, 2 orders of magnitude less than the avalanche/debris flow phases. Progressive glacier retreat and permafrost degradation were likely the conditioning factors; precursor rockfall activity was noted at least ~6 months previous; thus, the mountain was primed to fail. The 13 May landslide was apparently triggered by rapid snowmelt, with debuttressing triggering the 16 May event.
