Little Middle Sister Col

As expected, rapid rise of temp as sun hit snow at 10-12. The snow was sticky and wet by the time we got down to treeline after the descent. We approached in at 5:30 am, got to 3/4 up the col at 11:33 down by 11:44. sun wasn't on col yet, we were in -8 on average for am. We had a great descent on recent storm snow ( approx 10 cm ) from last night's storm. It was sitting on the seasons snow pack which was significantly rounded and bonded. The boot pack up col was very stable. We never saw signs of instability riding down but avoided all wind slab, and convex rolls. We felt on sind slab on convex roll near the bottom of our boot pack. We avoided it and it seems obvious to see.
