Sled access up to 21 km all the way to the cabin. The trail breaking was deep but access fairly easy to the run near the end of the valley (mind the open creek). After our first run the wind pick up and a first small slide stopped right a the main bench just below where we stop. On our way back up for a second run, a bigger avalanche carrying a lot of momentum, landed at same spot as the first one. Seemed to be coming from the rocky peak lookers right of the valley (N facing). We decided to bail from our second lap as thing were getting heated up there.
