I did the exact same run on Sat and noticed the same conditions, each turn on my board sent sluff down the entire gully. Defiantely felt good to rock carves through a natural quarter pipe on the left with a rock face to the right.
You didnt happen to see a snowboarder with a red/tan jacket and black pants in the gully while you were there did you? I waited at the top for a couple skiers to finish their climb and there were a few on the boot ladder as I came down. Wonder if one of em was you. Sherbie wasnt opend for very far and what was had some real thin cover with a few spots I had to walk across. The weather wasnt to bad though minus that one brief period of hail that hit right as I reached the top of the gully. It was even sunny for a little bit in there.
