Been working on this for a few weeks. Hardest part was shoveling all the snow into the big pile and packing it down. That took a few storms' worth of snow. Hard to tell from the pic, but the outside dimensions are about 8' long, 6' wide, and 5' tall. Inside is big enough for two average size people to sleep very uncomfortably. Still need to add the CO2 escape vents. Probably poke those vent holes from the inside toward the outside, on the theory that exit wounds are usually more of a mess than entry wounds.....easier to patch up the outside. This would be much easier with perfect "snowman" snow, but we've had wet snow, dry snow, ice, single digit temps, etc. So conditions aren't optimal. Not enough snow to make a real snow cave with elevated sleeping shelves, cold trench, etc. This is just made with what's available. Not sure if I'll sleep in it...I don't do really well in closed in spaces, plus the neighbors are already giving me strange looks and holding their kids' hands a little tighter.
