Best materials for building rock wall shelters?

Choosing the Right Rock Materials

When selecting rocks for a wall shelter, look for flat, sturdy stones that can withstand snow and wind loads. Aim for rocks with a rough texture to prevent slipping and ensure a secure foundation. For the base course, use larger rocks, roughly 12-18 inches in diameter, and space them 2-3 feet apart for optimal stability.

Building Techniques for Rock Wall Shelters

To build a rock wall shelter, start by creating a foundation using a trench or a series of holes for the base course rocks. Pack the soil around the rocks to create a stable base. For each subsequent course, use smaller rocks and pack them tightly around the previous course. This process can be repeated up to 3-4 courses, depending on the shelter’s desired height and the available materials. Consider using a mix of small and large rocks to create a stable and wind-resistant wall.

Anchoring a Tarp for Wind Protection

To ensure a tarp stays securely in place during strong winds, anchor it using a combination of rocks, sticks, and rope. Dig a shallow trench for the tarp’s edges and place rocks along the bottom to prevent the tarp from shifting. Tie the tarp to nearby trees or rocks using sturdy rope and secure it with sticks or rocks to prevent it from flapping in the wind. This will provide a stable and wind-protected shelter above treeline.
