Yeah, their approach is not indicative of "highly experienced backcountry skiers" for this tour. The standard route up the Battleship is to ski down from the Ophir pass parking area towards the power transfer station, veer off towards the creek, cross it and then begin skinning up the skin track that ascends up through dense timber on the northeast area of Battleship.
Last season I skied off the Battleship on various aspects roughly 15-20 times. I exclusively tour these days in the Red Mountain Pass area. I'm by no means, an expert of that area. There are folks I know who ski that zone all the time. I've never heard of or seen people dropping into that shot they were ascending from the top, or skinning it from the bottom. Its simply too exposed from above -with tons of hang fire from below. The times I've skied off the west/northwest side of Battleship (the side opposite why 550), I've gone off either straight north nose-skiing dense timber, or I've eased in near tree-line on the west side- skier's right.
I have ascended up the west side before on the far skinner's left through dense timber-emerging just below the main summit approach ridge on a protected nob. I've never considered skinning up the gut of the west/northwest bowl- even in relatively stable conditions- simply too risky and really, nowhere to run if something lets loose.
