Quick Answer
Best locations for constructing a snow cave in the backcountry are areas with deep, stable snowpack, often found near the base of north-facing slopes or in shaded valleys.
Ideal Snow Conditions
When searching for the perfect spot to build a snow cave, look for areas with snow depths of at least 4 feet and an average temperature below freezing. This will provide a stable base and prevent the snow from collapsing. Check for areas with a smooth, even surface and avoid slopes with rocky or icy patches.
Slope Orientation and Angle
When selecting a spot, choose a north-facing slope with an angle between 30 and 40 degrees. This orientation will minimize the amount of direct sunlight and prevent the snow from melting or collapsing. Avoid south-facing slopes, as they receive direct sunlight and are more prone to melting. A gentle slope is also essential, as it will allow you to easily dig and shape the snow.
Finding a Safe Snow Wall
When digging into the snow, look for a spot with a natural snow wall or a thick snowbank. This will provide the necessary support and structure for your snow cave. Use your shovel to dig a trench in the snow wall, starting from the bottom and working your way up. This will help you create a stable and secure entrance to your snow cave.
