Low doesn’t mean No avalanches. And the snowpack is still made up of junk. The day had been bluebird, mild temps with very little wind. Until a summit of Cirque peak where we experienced mod-strong winds in the afternoon. Alpine conditions were highly variable with bulletproof wind hammered surfaces or rotten facet junk. Ski crampons would almost have made travel easier. Also noted a 2-3cm very solid melt freeze/sun crust on solar aspects up to/around 2400m. We had a successful alpine mission until descending off Cirque Forepeak. Second skier triggered a wind slab at the top of a cross loaded gully which propagated up onto a more open slope. The avalanche stepped down to the basal/early season crust and continued to entrain facets and depth hoar. Skier narrowly managed to ski out of it with no injuries but lost some equipment.
