Yeah we don’t do deep pack to be honest, we do consistent pack. I’d wager 12-18” is a zone we live in most winters for a long period of time. Like you said, this pack is essentially a 6” block of ice with 6” of recent synoptic snow on top of it.
The Stake is really only one more event away from normal too. 10” under normal can be easily made up. Tonight might get closer.
