From Zander Strathearn:
Enjoyed your blog for a while and just thought I would send you a couple shots from around hanging lake today. 

There were probably 15 tourers that came up from the Callahan along with three sledders that did cross into the watershed but were in the hanging lake area. 


First photo is skier triggered on a very steep unsupported south aspect, you can see the people.  There was a firm layer that probably caused by warm air/wind about 20cm down in localised pockets through the area.   Second photo was triggered by sleds remotely I think about 50 m away from the tracks on a north aspect.

Avalanche Canada MIN Reports:

Spearhead Conditions: Dec 24, 2018

Hanging Lake Area: Dec 24, 2018




From South Coast Touring:
Bram Whillock

Conditions update from the spearhead.
Things at this point have filled in nicely and the zone is skiing quite well. Harnesses and rope was brought but never deployed. As you can see from photos there are still significant slots on both the spearman and decker glaciers, but they are quite avoidable in good visibility. There are some surprising holes while skinning high near the Cham chute entrances so keep your wits around there.
Cham 3 is filled enough to ski but quite crusty. Cham 2 looks good as well. Cham 1 is way too rocky. Vista bowl is fairly rocky at the top. Vista chute in good shape as well. Decker 9th hole well filled with some cornice debris, currently a short drop over the cornice to get in.
Windward and rocky areas are extremely poorly filled in. You have to walk from the base of decker through the rock field to ski out decker creek. Upper disease ridge is extremely rocky and unskinnable. Bootpacking is rugged, rocky areas are still faceted and it makes for tricky boot packing.
Merry Xmas shredders!
