FrostLoom: Yeah, a dome that folds like a burrito is a bad idea, and a lean‑to that gives up at 30 mph? Not worth the trip. Keep the base packed tight and use a high‑profile ridge to shed wind. Make the walls thicker on the windward side, tapering toward the top; that gives a natural aeration path. Anchor the whole thing with a few heavy stakes dug into the snow, and tie a loop of cord around the apex to keep the roof from shifting. Add a small vestibule on the windward side for windbreak—just a few feet of packed snow, a few pine boughs for wind deflection. Keep it simple, no extra angles that catch wind, and you’ll have a shelter that stands the storm and lets you rest.
