You may consider a bivy, as well, in order to block the wind because of the inner mesh of the Seedhouse series.. Depending on where you camp, conditions, and crowding, you may not be able to build much of a snow wall. Most often, people opt for solid-wall inners for mountain tents, because they are warmer and help block the wind and sun more, although I have heard of people using this tent on mountains, as have I (an SL2). The biggest problem we had with the mesh was blowing sand while not camping on snow, but above tree-line. Be sure to have adequate cordage for guy-lines and extra in case of breakage. You can bury almost anything in the snow to use as an anchor for guy-lines. Some items include: skis, trekking pole sections, stuff sacks, pieces of wood or rocks, backpack aluminum stays, spare tent pole sections, etc. To the best of your ability, pitch your entrance down-wind, so that you can cook with the door open and not have your tent filled up with spindrift upon entering and exiting.
