Two recent very large (size 3) avalanches were observed in the Joffre Lakes area on Saturday. These released from the high alpine northeast and northwest faces of Mt. Joffre and Mt. Matier, respectively. The evidence of the Mt. Matier slide features several 'step downs' as the slide progressively triggered deeper layers of the snowpack, all the way down to previous summer snow cover. Both slides likely released during last week's storm.Please submit any observations you have to the Mountain Information Network here.

The storm from early last week produced ample precipitation, however it mostly fell as rain. Extreme out of the south and southwest likely produced widespread cornices and wind slabs in lee terrain during the storm. These problems are expected to be on a positive track toward stabilizing.A MIN from Friday suggests that it's skiable from about 1600 metres on up. Between 1600 and 2000 m there is 5 to 10 cm of low density snow over a 5 cm breakable crust. Above 2000m is reportedly skiing well and alpine snowpack depths are approaching 175 cm. Near the ground there is a crust/facet interface. Although little is known about the reactivity of this layer, recent observations in the north of the region show that it was reactive during last week's storm. It is thought that there is insufficient snow for avalanches below 1500 m.
