i did it in sweden a few years ago and thought i would post it.. we dug the holes out of a snow drift.it took about4 hours to do.it had 2 shelfs for sleeping on and a hole made with the fishing auger to let air in.and had a few candles dug into the snow to indicate that we still had air .we used deer sleeping mats to insulate us.they were pritty good. a swedish guy said that they are warm to sleep in.i recon he lied. we woke up at about 3 in the morning freezing. so went for a sauna. any one else got any experiances.
