Quick Answer
Packing snow into walls involves compressing snow to a density of 0.4-0.6 grams per cubic centimeter, creating a stable structure. This is typically achieved using a technique called "puddling" or "ramming." A simple tool like a shovel or a snow board can be used to pack the snow.
Creating a Stable Foundation
When building a snow wall, it’s essential to start with a solid foundation. Dig a trench for the wall base, about 6-8 inches deep and 12-18 inches wide. Fill this trench with compacted snow, using your shovel or snow board to pack it down to a density of 0.5 grams per cubic centimeter. This will provide a stable base for your wall.
Puddling and Ramming
To create the wall itself, you’ll use the “puddling” technique. Fill a snow bucket or a large container with snow, and then pack it down to a density of 0.4-0.6 grams per cubic centimeter by stomping on it or using a snow board. This process, called “puddling,” should take around 10-15 minutes, depending on the snow quality and your physical effort. Once the snow is packed, use a shovel or snow board to “ram” it into the wall, creating a solid, compact layer. Repeat this process, adding new layers of snow and repeating the puddling and ramming process until your wall reaches the desired height.
