Quick Answer
To construct a snow cave sleeping platform, start by excavating a pit with a flat bottom, then create a circular wall and shape it into a dome. Build the sleeping platform using sturdy snow blocks, ideally with a diameter of 6-8 feet and a height of 3-4 feet. Ensure the platform is sturdy and level.
Snow Cave Preparation
When constructing a snow cave, begin by choosing a site with a natural snow pit or a spot with deep, powdery snow. Ensure the area is clear of obstacles and any weak snow that could collapse. Use your shovel or a makeshift tool to dig a pit with a flat bottom and a diameter of about 6-8 feet.
Snow Block Construction
To build the sleeping platform, create sturdy snow blocks by packing the snow into a rectangular shape and then compressing it using your body weight or a shovel. Aim for blocks that are about 1-2 feet wide, 2-3 feet long, and 4-6 inches thick. Use these blocks to construct the platform, stacking them on top of each other to create a sturdy base.
Platform Shaping and Finishing
Once you’ve built the platform, use your shovel or a makeshift tool to shape the surrounding snow into a circular wall. The wall should be about 3-4 feet high and 6-8 feet in diameter. Use additional snow blocks to reinforce the wall and create a sturdy roof. Finally, shape the platform to create a comfortable sleeping surface, ideally with a slight incline to ensure good drainage.
