Skied 6 of 7 steps from Asulkan this morning.

Everything above the hut is wind blown, compact, below was more wind loaded

Below the Pterodactyl we were skiing a short path, both commented on the wind slab / potential for avalanche before first skier entered , ski cut did not trigger anything, second jump turn caused the slab to go, didn’t run far

Essentially the same thing occurred 100m down slope as we traversed across towards the ridge

Valley bottom looked very low tide, rocky. Large openings in the glacier , had to ski far skiers right

You can see debris on FatMaps where previous slides occurred, I marked where ours happened
