A skier intentionally triggered an avalanche in Argentina bowl below south Saddle Peak. The avalanche broke 2 feet deep and ran 1000–2000 vertical feet piling debris 20 feet deep in the run out zone and breaking trees. Photo: anonymous

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.”
Did a few laps on third meadow, and dug a pit. The pit resulted in two failures without propagation pleasant skiing all the way down (new snow on top of old powder turns).
45.48054, -111.01267
~120cm depth
Facets forming on top in sun
ECTN5 failed 80cm above ground
ECTN25 failed 30cm above ground
I went full barbarian on the column after 30 taps, and couldn’t get it to slide on the facets in the ground.
Profile: Sugary facets 0-20cm; 1F 20-30cm; 1F crust @30cm, 4F 30-70. Fist 70-125cm (0cm is the ground).
Very visible buried surface hoar layer was not producing ECT results so we cut a PST and got 30/100end. HS ranged from 105-135cm on leeward slopes and near 60cm on windward.
While going for a walk up the main fork of hyalite today I spotted this crown below the upper cliffs on the maid of the mist
Multiple large avalanches on different bowls and different aspects of Cedar. Photos taken from Yellowstone Club by YC Ski Patrol. NE and E aspects. Both approximately 9400 feet elevation. Shaded photo is N aspect, photo with sun and shade is NE.
A small slide was remotely triggered by the second skier catching up to the first skier. We were skiing mellow terrain on the east side of a small ridge and remotely triggered the slide at a roll over point on the north aspect of the ridge. Prior to skiing we conducted an extended column test on a near by north slope with good results but kept our path mellow do to some wind affect areas we noticed on the west side of the ridges. We skied to the debris pile after the slide stopped to take a picture and would estimate it broke 30 cm down at the base of the new snow over the last week.
Just wanted to send in a quick ob about snowfall.. in the last 24 hours at the Roost it snowed about 4 inches despite Fisher recording 0 inches of SWE
