Went up to kindergarten couloir this morning, when we were making our way up the right of the fan we saw what looked to be a size 2 loose dry avalanche come down the couloir, when we headed up the start zone was about halfway up and most likely was caused by a cornice dropping as there was large debris that came down as well, no slab released, had some new snow that day that caught speed down the middle, ran about 3/4 of the fan. this is my first report here so hope this helps!

Snow conditions were: Hard, Powder. Weather conditions were: Cloudy, Windy. We rode: Steep slopes. We avoided: Sunny slopes. Riding quality was good.


size 2 dry loose, started about halfway up the couloir and ran 3/4 of the fan, seemed to be caused by Cornice dropping,
