To get a shelter in the desert, particularly a basic and effective one using readily available materials, you can construct a trench shelter. This type of shelter leverages the natural insulating properties of the earth to provide protection from extreme desert temperatures, wind, and sun.
Building a Basic Desert Trench Shelter
A desert trench shelter is a practical and relatively simple structure designed to offer crucial protection in harsh desert environments. It primarily involves digging down into the earth to escape the direct sun and wind, then using the excavated material to create protective walls.
Step-by-Step Construction
Based on the principles of desert survival and the provided reference, here's how to construct a basic trench shelter:
-
Step 1: Dig a Trench
- Begin by digging a trench in the ground. This initial step is fundamental, as the trench forms the core of your shelter, providing a sunken area that offers natural insulation and concealment. The depth and length should be sufficient to comfortably accommodate you, allowing you to lie down and shield yourself from direct exposure. Choosing a location that might already offer some natural shade (like near a rock formation or dune) can enhance the shelter's effectiveness.
-
Step 2: Create Berms
- Once your trench is established, place the sand you unearthed around three sides of the trench. These mounds of sand, known as berms, act as walls, significantly enhancing the shelter's protective capabilities. By building these berms around three sides, you create barriers against prevailing winds and direct sunlight, further increasing the interior's coolness and reducing exposure to blowing sand. This also helps to define the structure of your shelter.
-
Step 3: Establish an Entrance
- Remove additional sand from one end of the trench so you can get in and out easily. This designated open end serves as your entrance and exit point. Ensuring clear and easy access is crucial for quick entry or departure, especially in an emergency. This design allows for a single, controlled access point while the other three sides are fortified, maximizing protection.
Key Considerations for Desert Shelters
Constructing an effective desert shelter involves more than just digging; it requires strategic planning to maximize safety and comfort.
- Location Selection: Choose a site that offers natural advantages. Look for elevated ground to avoid flash floods, but also consider areas that might provide natural shade during the hottest parts of the day, such as the leeward side of large rocks or dunes. Avoid areas prone to collapse or those that might attract dangerous wildlife.
- Protection from Elements: The primary goal is to mitigate the desert's extremes:
- Sun: The trench itself offers relief from direct sunlight. Covering the top with a tarp, branches, or even clothing (if available) can provide additional shade and reduce radiative heat.
- Wind & Sand: The sand berms built in Step 2 are crucial for blocking wind and preventing sand from blowing directly into your shelter. Orienting the open end away from the prevailing wind direction is also beneficial.
- Heat (Day) & Cold (Night): The earth acts as an insulator, keeping the trench relatively cooler during the day and warmer at night compared to surface temperatures.
- Material Utilization: In a desert environment, materials are scarce. Focus on using what's available: sand, rocks, and any sparse vegetation (like tough desert shrubs or dead branches) for structural support or overhead cover.
- Hydration: While not directly part of shelter building, remember that a shelter's effectiveness is tied to your overall desert survival strategy. Conserving water and staying hydrated are paramount, and a good shelter helps by reducing perspiration and heat stress.
Building a trench shelter is a fundamental skill for desert survival, offering a vital refuge against the harsh conditions.
