The bottom photo is the first I have actually seen of "a" or "
the" avi off what appears to be the north shoulder, east side of Warner. Is that a photo of the slope that actually slide....or just one of the slopes that slide? The trail map drawing and red shaded area shows avis running off the top of Warner (16:1) and off that north shoulder. The one actual terrain photo seems to match the terrain for the north shoulder.. Does anyone posting here know what part of the mountain actually did slide? Photos? Just for historical context, like Jerry wrote above I have never seen a slide of any size in that area while the ski area was *
open* to the public
, going back to the Jackass days. Never seen a slide from the top of Warner either. But the bare ground of Warner and the historical avalanche paths (from the top of Warner literally into the town of Warner 3500'+ below) tell us it has happened in the past. There were similar slides (nothing this big thought) I can remember on the exact same slope during major storm events that generally occurred at night (I saw them while grooming the run below the debris field). Just nothing as big as what the two were in this incident. But worth noting the slide area shown in the photo and the area around/above/beside it got a
lot more skier traffic when it was just the one original lift available to skiers on the mountain. As well as the bottom of that particular slope being undercut consistently by the ski area snow machines while grooming.
In the '80s a woman was injured in a small avi on top, west side of Sheer Bliss. Never known of control efforts by the ski area besides just skier traffic, any where past the east ridge line and summit of Warner. When the area changed boundary lines to incorporate the west side of Warner did that change? During the '70s there were 12 distinct bomb sites (pillows or cornices) on the ridge from the start of the Warner traverse going up the ridge ending at the top of Warner (16:1's) biggest open slope.
I read this above, "They blasted the Wardner in the morning and shortly after it opened up it happened." And from Bill's FB post, "Our understanding was avalanche mitigation with explosive charges had been completed off the top of Wardner Peak before skiers and boarders entered the then uncut traverse.". Lots of terrain covered in those two statements. Does anyone know if the Patrol ski cut or bombed the ridge going up Warner the morning of the avalanche? Was the top of 16:1 (Warner Summit) bombed or ski cut that morning, prior to opening? Anyone from the patrol hike over the top of Wardner and or ski into the west side bowl of Warner prior to opening?
In the Silverhorn/Jackass days it was common for Warner to stay closed 12 to 36 hrs after a major storm event. This when there was only one chair and the public pressure to open Wardner was very high. Unsuspected then, the lack of man power and resulting time lags to open Wardner might well have been the best control technique we had at the time.
As an after thought. From the opening of the area in the late '60s and the one chair, it was typically un-skied Kellogg Peak (now Skyway Ridge) that was seen a bigger threat than Wardner as a avi area. Simply because Kellogg wasn't controlled often and saw little to no skier traffic while threatening a large portion of the terrain skiers did use. String lines of 100 sticks of dynamite and or rope cutting the cornice was common there. Hard to visualize any of that now with the change in skier traffic patterns.
From the debris field being reported as 10' deep and my own experience in the ski area, and on Warner specifically, I have no doubt the storm that night was a unique wind event with the resulting snow load. Tragic for all involved. So sorry for that.
Just trying to learn something from it. Thanks. Be careful out there!
