Which rock types provide the best shelter from elements?

Choosing the Right Rock Formation

When selecting a rock outcrop for shelter, look for formations that are at least 3-4 feet thick and have a stable base. A sloping or overhanging ledge is ideal, as it allows snow to slide off and reduces the risk of rockfall. Consider the orientation of the outcrop, as a south-facing slope can be too hot during the summer months. Aim for a spot with a relatively flat surface, which can be achieved by excavating a shallow trench.

Rock Types and Their Characteristics

Granite is a popular choice for shelter due to its durability and resistance to weathering. It can be found in a range of colors, but dark-colored granite tends to be more stable. Basalt is another excellent option, as it is highly resistant to erosion and can withstand extreme temperatures. Gneiss is a metamorphic rock that is often found in mountainous regions and offers excellent protection from the elements. When in doubt, examine the rock closely for signs of weathering, such as cracks or staining.

Building a Shelter

Once you’ve selected a suitable rock outcrop, begin by clearing any debris or loose rocks from the area. Use a sturdy branch or rock to create a makeshift shovel, and dig a shallow trench to create a flat surface. If the rock is too rough, use a piece of cloth or a rock to smooth out the surface. Add insulation such as leaves or pine needles to the shelter, and consider creating a windbreak using branches or rocks. Always prioritize stability and safety when building a shelter, and be prepared to evacuate if the weather deteriorates.
