Part of this decision depends on how much snow you have. Take into account length, depth and height as you estimate the amount of snow you’ll need. Four feet is usually an adequate height. [1] X Research source
Alternatively, pour cold water over the snow to make a layer of ice. If you’re planning to dig a tunnel, leave a space with no water poured over it so you can dig more easily.
If you’re using bricks, work like a bricklayer: put down one layer, leaving a few inches (or centimeters) between each brick, and stacking the next level so that each brick straddles two underneath it. Have another person follow you by packing snow in between the bricks. If you’re digging a fort into a snowdrift, use a shovel or your hands and burrow your way into the pile. Once you’ve made your entrance, clear out a room from the inside with your hands or a small shovel.
Work from the bottom up to avoid ice overbearing the top and collapsing. [7] X Research source Make sure it’s below freezing outside when you do this so the water turns quickly into ice. [8] X Research source
