Quick Answer
To ensure proper airflow in a rock outcrop shelter, create a ventilation system by digging a small drainage ditch near the entrance and using rocks to create a windcatcher that directs airflow into the shelter. This helps to remove stale air and prevent the buildup of heat.
Creating a Drainage System
When building a rock outcrop shelter, proper drainage is crucial to maintaining airflow. Dig a small ditch, about 6-8 inches deep and 12-18 inches wide, near the entrance of the shelter. This will direct water away from the entrance and prevent it from accumulating inside the shelter. Make sure the ditch is at a slight angle to prevent water from flowing back into the shelter.
Building a Windcatcher
To maximize airflow, create a windcatcher by placing rocks on top of each other, forming a narrow opening at the top. The windcatcher should be about 2-3 feet in diameter and 1-2 feet tall. This will allow wind to enter the shelter while keeping debris and rain out. Experiment with different rock configurations to find the optimal balance between airflow and protection from the elements.
Tips for Shaping the Shelter
To ensure proper airflow, avoid building the shelter in a way that creates a dead air space. Instead, use rocks to create a sloping roof that allows wind to flow over the top of the shelter. Keep the walls of the shelter about 3-4 feet high to allow for easy ventilation. By creating a well-ventilated shelter, you can stay safe and comfortable while enjoying the protective benefits of a rock outcrop shelter.
