Location of Observation: Oaks gulf
At approximately 12:35 we watch a skier trigger an avalanche, it run about 200-400ft from somewhere in the airplane area of Oaks gulf. It was hard to see exactly what gully he was in. The skier appeared to be ok. We were skiing the Main Gully on the other side of oaks. Our Group at around 12:40 trigger a small avalanche just above the bend in the Main gully, we were still on the south aspect of the upper portion of the line, the steep roll was just below us and we were at tree line. That area has several skiable lines. We started to push toward the skiers right on to a lower angle slope under 30 degrees (i took a slope angle measurement 27) and the slope above us was more of a southeast aspect and steeper. At 12:45 We triggered our second avalanche. The Slope that was a above us. We trigger the slab from the bottom edge. The crown line was about 100 to 200 vertical feet above us and about 60m wide. The skier that trigger the slab was on the edge and was able to make it to and grab a clump of trees maybe 4 to 5 ft of travel, he was burial up to his waist. we recovered our friend, transited and started skin out the line we had just skied being vary careful of what was above us and the slope angle we were on. To days take way don’t under estimate our ability to trigger and release touchy wind slabs from the bottom of the slab.
