Quick Answer
Hard-packed and granular snow types make better cave walls due to their stability and durability. These types of snow offer less risk of collapse and are more resistant to melting and erosion. They provide a safer and more reliable shelter option.
Choosing the Right Snow Type
When selecting a snow type for a cave wall, it’s essential to look for hard-packed and granular snow. This type of snow is typically found in areas where the temperature has fluctuated, causing the snow to become more dense and resistant to melting. To identify a suitable snow type, look for areas with a consistent temperature, wind protection, and a history of snow accumulation.
Measuring Snow Stability
To assess the stability of the snow, perform a simple test called the “finger test.” Insert your finger into the snow at a 45-degree angle, and if it holds your weight, the snow is suitable for a cave wall. If the snow collapses or crumbles, it’s not stable enough. This technique allows you to evaluate the snow’s density and structure in a quick and non-invasive manner.
Building Techniques for Cave Walls
When constructing a cave wall, use a technique called “block stacking.” This involves breaking the snow into blocks, typically 2-3 feet thick, and stacking them on top of each other. Use a rope or a makeshift pulley system to lift the blocks into place, and secure them with snow anchors or ice axes. This technique allows you to create sturdy and stable walls that can support the weight of the snow above and provide a safe shelter.
