Accident Report
Alta Lakes, north of Ophir - CO
Accident Summary
Entering into gold king basin we had signs of wind loading from the southwest accumulating on the sides of the Alta lakes roads, with collapsing. However this was at 11,300 elevation on the road. No signs of instability on the climb as the route we climb on the south face had slid in the previous week. On top of the ridge significantly wind blown with little to no base just under on south face. The top of the couloir was extremely firm but held a decent edge. Given my previous sighting of a major slid and a small slide lower skiers left, We decided to drop. As I safetied to the skiers right at the bottom of the couloir I noticed some wind loading but it felt mostly stable. No shooting cracks, no instability, no rumbling or whomping. Second skier came down lost and edges just above my safety spot and triggered the slab to go. Be mindful out there wind is tricky even when your studying your line for over a month.
