Skier triggered avalanche in Argentina Bowl

From IG Messages: “as expected, broke a slide out while ski cutting saddle today. Here’s the report. 

After summiting south saddle peak, we noticed wind loaded snow on top of an old avalanche crown (maybe 4-5 days old - 2’ deep). We made the decision to ski cut high, hoping to break out the new wind drifted snow. We were the first ones out there today with just a party of two still on north summit. No one below us. I was able to get several small pockets to pop before a larger pocket broke, triggering a sympathetic slab down lower in Argentina bowl. Both slides ran 1000-2000’ into the flats down low (crossing the standard traverse). Debris piled up 20’ deep and broke trees up to 6” in diameter. Slow start, but picked up lots of steam. We skied lower and found good snow below the ridge where there was less wind effect.”
