Stadium area

Icy dust on crust to 1200 meters. Exit Gully ran size 2 during the storm, likely on Sunday. Steep trees skin-up track beside Home run ran on Sunday size 1 Creek on Skiers left of Home run is actually more exposed than last week, despite the rest of the run having a meter of fresh snow. Cleavage Couloir ran from a crown on the rock cliffs at the top size 2.5, stopping just short of Shannon creek gully. Could not see whether the round the corner entrance at very top of Cleavage had avalanched. Took the skin track up through the trees west of Stadium Gully Left. Visibility was poor, but it looked like areas of Stadium Gully Right and Moraines avalanched during the storm. Did a pit at 1530m, 37° slope, NNE aspect. HS >300cm HST 102 cm Crusts at 30, 64, 100(pre storm crust layer) F to 15 4F 15-30 1F 35-100 Storm snow at 1550 is nicely right side up and supportive. (Ski Pen about 25cm) Shovel shears showed planar results at 30,60 and 100 cm Compression test CTM 15 sudden planar on crust at 100. Pop and drop Second test same pit CTM 13 sudden planar on crust at 100 Above 1550 in the alpine we started seeing more wind effect and chose to ski Stadium Gully Left as it is well supported. Ski cut a 35°convexity at the top of run with no result. The snow itself was quite supportive and it was hard to get a lot of energy into the ski cut. There was some wind effect on the gully snow but it skiied pretty nicely. Then did two more runs in the trees west of Stadium left with supportive creamy and dreamy powder. Summary- the 100 cm storm snow does not seem to be particularly well bonded to the crust interface below it. We saw a lot of evidence of crowns in rocky steep shallow areas, and believe that interface could still be reactive in steep areas that did not slide during the storm. In the deeper, less steep storm snow areas it would take a lot of energy to trigger that layer and supported slopes skied well with no signs of instability.
