In his guidebook Dave makes a point of explaining that the only winter mountaineering that really goes on in the Selkirks is ski mountaineering, and the reasons (snowpack, avalanches, and weather) why this is so. Only something like 3 of the technical (non-ski) routes in the whole Selkirks South guide had had winter ascents at the time he wrote the book, although I believe Greg Hill's pushed that a bit since then.....
