Hey, take it slow. First, make sure the snow you’re using is packed and fresh – wet snow that’s been compacted a few times works best. Start with a thick base, like a few feet high, and build it up in a straight line, a sort of spine that runs from the entrance to the back. Keep the walls vertical, about 10 to 12 degrees from the ground, and use a smaller inner wall if you can – that helps hold the weight. Every few inches, smooth the snow and press it with your hands or a shovel to remove air pockets. If you’re still worried, put a wooden pole or a sturdy stick through the center, like a makeshift support. Remember, patience is key – let the snow settle for a bit before you add the next layer. Good luck, and enjoy the quiet.
