Quick Answer
For a reliable fire above treeline, consider using birch, aspen, or juniper wood, as they are widely available, dry quickly, and produce minimal smoke.
Choosing the Right Firewood
When selecting firewood above treeline, prioritizing dryness and density is crucial. Birch and aspen wood are ideal options due to their low moisture content and high BTU value. Aim for wood with a moisture level below 20% for efficient burning. Look for logs with a diameter of at least 3 inches to ensure they burn for an extended period.
Preparing the Wood
Above 8,000 feet, the air is too thin to dry wood quickly. To compensate, split the wood into smaller pieces, exposing more surface area to the elements. This technique can reduce the moisture content by 10-15% in just a few days. Store the split wood in a sheltered area, protected from wind and precipitation.
Building an Efficient Fire
When building a fire above treeline, use a lean-to or teepee structure to maximize airflow. Start with a small fire and gradually add larger logs as the fire grows. Use kindling, such as dry grass or small twigs, to ignite the fire. Aim for a fire that burns hot and clean, producing minimal smoke and soot. This will help conserve energy and minimize the risk of carbon monoxide poisoning in high-altitude environments.
