Agreed avalung is a lifesaver in a treewell. But if you don't have one (I don't) getting rightside up is the only way to have a chance of getting yourself out. Having beein upside down in treewells two times, I can tell you that my partners were right next to me--not ten feet away--and in both cases, they never saw me go under. I had to get myself out. I calmed myslef, got out of my bindings and climbed the tree.
BlurredElevens, commonlaw, and SheRa have it exactly right in my opinion. No pole straps -- ever. And if upside down in a treewell, get out of your skis and get your feet under you. Hanging upside down and waiting for someone to pull you out is no plan for survival.
I boiled my thermometer, and sure enough, this spot, which purported to be two thousand feet higher than the locality of the hotel, turned out to be nine thousand feet LOWER. Thus the fact was clearly demonstrated that, ABOVE A CERTAIN POINT, THE HIGHER A POINT SEEMS TO BE, THE LOWER IT ACTUALLY IS. Our ascent itself was a great achievement, but this contribution to science was an inconceivably greater matter.
