Quick Answer
In extremely cold weather above treeline, building a fire becomes a significant challenge due to reduced oxygen levels, strong winds, and low humidity, making it essential to use efficient techniques and equipment.
Weather Conditions and Fire Building
Above treeline, the air is thinner, and temperatures are colder. At an altitude of 13,000 feet (4,000 meters), the air pressure is about 40% of what it is at sea level, which significantly reduces the oxygen available for combustion. This means that fires will not burn as hot or efficiently, and they may struggle to get started in the first place. To combat this, it’s essential to use high-efficiency fire starters, such as ferrocerium rods or magnesium strikers, which can generate a large amount of sparks and heat.
Fire Pit Construction and Wind Protection
In windy conditions, it’s crucial to build a fire pit that can contain the flames and protect them from the elements. This can be achieved by digging a shallow pit and lining it with rocks, which will help to reflect heat and protect the fire from wind. A windbreak, such as a wall or a trench, can also be constructed to shield the fire from direct wind. The fire should be built in a way that allows for good airflow, but not so much that it gets extinguished by the wind.
Fire Starting Techniques and Equipment
When building a fire in cold weather above treeline, it’s essential to use techniques and equipment that can generate a lot of heat and sparks. This can include using a bow drill, hand drill, or other forms of friction fire starting, which can generate a lot of heat and sparks. A good fire starter, such as a ferrocerium rod or magnesium striker, can also be used in conjunction with tinder and kindling to get the fire started quickly and efficiently.
