Attempted Kindergarten Couloir today. Conditions in the couloir left a lot to be desired, and as a result we turned around ~2/3 the way up the couloir. The fan and a large portion of the couloir are riddled with frozen debris from recent wet-loose slides. Where there wasn't debris we predominantly noted a firm and supportive crust interspersed with pockets of soft, dry snow anywhere from 5-15cm deep. We also noted isolated pockets of wind slabs around 5-8cm thick and not overly reactive nor large enough to be of huge concern. In the couloir itself there was no bonding at all between the softer surface snow and the underlying crust which lead to quite a bit of sluffing with the few turns we did get.
Despite a later start for this time of year (9am) it was around -7 in the parking lot and stayed in the negatives until we returned to the car around 1:30pm. The sun stayed behind the clouds for most of the day so solar effect in the couloir was minimal, and we only started to note the snow getting wet and heavy halfway down the trail from the lake.
