Sorry Dave, wasn't trying to ruffle feathers or cast aspersions on your Arctic expertise. My comments were based on the snow coffin Uncle Ray Mears created in that video, which would certainly take more than 10 minutes to build! And the pine boughs are an essential part of that build, to provide floor insulation below your sleeping bag, the thicker the better. I'm not convinced even my Exped down 9LW would provide sufficient insulation in those conditions. And as he points out, it needs to be wide enough to stop your bag rubbing against the sides as you sleep. In a quinzy, you're normally sleeping on a shelf with a cold sink below you, a roof above you, relatively draft-free and hopefully with a candle or two to keep the temperature just a few degrees blow zero centigrade . In the snow coffin, you're actually sleeping in the cold sink!
And its the temperature that is my concern here. Last November, Jokmokk temp projections were between -10 to -14C. Yet i met temps in Jokkmokk that reached -24C even at 10pm in the city and considerably lower than that in the forests north of Jokkmokk where I was camping, along with considerable snowfall. Without a fall-back option like say a car or hot-tent, a snow coffin could become a literal one.
I disagree that putting up a tipi in the dark is dangerous. A decent head torch makes life very straight-forward, and a ten-minute job single-handed, even on my 8-man. (maybe add a few minutes to stomp down the snow first). That gets you out of the wind and snow immediately. Even if you don't have firewood for the first night for the wood stove, liquid fuel and/or alcohol stoves will raise the internal temperature quickly to above freezing (as long as you have adequate ventilation in the tent). Come daylight, you can get set up properly, get firewood etc.
I'm not saying don't try out quinzys, snow-scrapes etc. In fact I actively encourage it. After all, why go to the Arctic if you're not going to try out these things. its the whole point of the trip! However, I'd politely suggest getting settled in first, rather than planning on relying on a snow-scrape as your primary option on the first night of the adventure. What happens if the temperature suddenly plummets, and you end up wet and on the verge of hypothermia. What then? After two to three minutes without my gloves on at around -15C, I could no longer operate a tent zip effectively. Add another 10-15C of chill to that temp, and your hands become useless, and your reasoning ability plummets. You are physically incapable of lighting match, ferro rod or a lighter, or firing up a stove. You are now in what scuba instructors love to refer to as the "vortex of death"....
I'll just say If people want to sleep in tents they will do. And on the first night I wont be setting my tent up, I'll be sleeping outside, not on pine boughs as I have done before, and I'll be fine, thankyou Andy. I'll send you a piccie.
