Written up on the Landslide Blog with analysis by Drew Brayshaw of Statlu Environmental Consulting. 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.  “

This failure of the lookers right rock buttress of the NE face of Joffre resulted in the elimination of Twisting Couloir from the tick-list of steep ski lines.

Also written up on the Landslide Blog this definitely catapaults Joffre into the category of Known Producer. According to Dave Petley, this seems larger than the previous slide and involved the rock buttress in the centre of Joffre failing thus wiping out the top two thirds of the Central Couloir.

Shot from the side of Joffre Peak. Steep as it looks. That’s the face that Matt Bodkin and Andre Ike skied direct from the Peak to Twisting in the late 90s I believe? I followed their tracks down and skied Twisting. Our tracks were probably right along the line of the fracture where the hanging glacier fell to its death along with the rest of the snow and ice on Joffre.

Comment from Drew Brayshaw in Gripped Magazine citing a National Post interview – ““As soon as I saw the scar of that second landslide, which was right next to the first, it is obvious that the failure plane is continuing through the mountain, it is almost vertical,” ….“That strongly suggests that the next buttress over on the face of the mountain … I would say is more likely than not, going to fall off. The question is just when.”

Annotated by Drew Brayshaw. Picture by Gerry Kollmus May 18, 2019 – Red circle indicates the brand new crack. Notice its trend? Green line is existing features on the next buttress over which directly line up with the trend of that new crack and the failure plane.


Rock, mud, ice and snow torrent from the first event gouged out Cerise Creek taking out both winter and summer trails and creating a new lakeScreenshot from Safarik video

Rock, mud, ice and snow torrent from the second event was even less gentle to Cerise Creek entraining debris in further in the newly-created lake and not being as gentle in negotiating the turn at the Check’s in the Mail slidepathPicture by Jamie May

First slide nearly reached the forest service road accessing the winter and summer Cerise Creek trails. Screenshot from Safarik video

Wilfried Braun picture showing the second slide aftermath. The runout of the second slide takes a wider turn at the Check’s In the Mail slidepath. It also overruns the junctions of the Cerise FSR and the FSR heading W to Pascall.
