Use dry inner bark or resinous wood as tinder. Create a sheltered area for the fire using a large leaf or rock. Keep the fire small and protected from wind and rain.
Travel at night when temperatures are lower. Rest during the day in the shade. Conserve water by avoiding talking and breathing through the nose.
Build a pile of snow and let it settle for a few hours. Dig a tunnel into the pile and create a sleeping platform. This provides excellent insulation.
Boil water for 1 minute to kill pathogens. At high altitudes, boil for 3 minutes. This is the most reliable method for killing bacteria and viruses.
Animal droppings can tell you what they eat and how healthy they are. Fresh droppings are soft and moist. Dry droppings are old. Look for hair or bone fragments.
Keep a bed of embers going overnight to restart the fire easily in the morning. Cover with ash to keep them smoldering but not burning.
Many plants have medicinal properties, but only use those you are certain about. Willow bark can be used for pain relief (contains salicylic acid). Avoid unknown plants.
Drink small amounts of water frequently rather than large amounts at once. Avoid salty or sugary foods that increase thirst.
Use dry leaves, pine needles, or grass as insulation under your sleeping bag. This prevents heat loss to the ground. Keep your sleeping bag dry.
Clean the blister with soap and water. If it needs draining, use a sterile needle to poke a small hole at the edge. Do not remove the skin. Cover with a bandage.
Observe the direction of the wind by watching smoke, dust, or moving vegetation. Consistent wind patterns can help you determine direction if you are lost.
Test berries one by one. If they cause a burning sensation in the mouth, spit them out. If they cause no reaction after 15 minutes, eat a small amount and wait 8 hours.
Build an A-frame structure using two poles and a ridgepole. Cover with layers of leaves, mud, or bark. This design sheds rain and snow effectively.
Boil water and collect the steam in a container. The condensed steam is pure water. This method removes salt and chemicals but requires energy and time.
Look for the direction of the track by the shape of the toe marks. The deepest part of the track is the heel. Follow the trail until it disappears or leads to a water source.
Use a piece of char cloth or a cotton ball soaked in petroleum jelly to catch a spark. Transfer the spark to the tinder bundle and blow gently to create a flame.
Use dry inner bark or resinous wood as tinder. Create a sheltered area for the fire using a large leaf or rock. Keep the fire small and protected from wind and rain.
Wear a wide-brimmed hat and cover exposed skin. Use a light-colored, loose-fitting shirt. Apply sunscreen if available. Avoid looking directly at the sun to prevent snow blindness or eye damage.
Dig a tunnel into a snowdrift or pile of snow. Create a sleeping platform slightly higher than the entrance to keep cold air out. Ventilation is crucial to prevent carbon dioxide buildup.
Use a portable water filter with a pore size of 0.2 microns or smaller to remove bacteria and protozoa. Pre-filter cloudy water through a cloth before filtering. Filters do not remove viruses.
Look for fresh kill sites, blood on vegetation, or disturbed ground. Predators often mark territory with scent or visual markers. If you see tracks, move away quietly.
Once the fire is established, push the logs together to create a bed of hot coals. This provides consistent heat for cooking and warmth without the need for constant feeding.
Water flowing from a tree stump or vine (if cut carefully and tested) can be a source. Avoid water that is stagnant, smelly, or green. Boiling is always recommended.
Travel at night when temperatures are lower. Rest during the day in the shade. Conserve water by avoiding talking and breathing through the nose.
Do not rub frostbitten skin. Warm the area gradually using body heat or warm (not hot) water. Do not walk on frostbitten feet if possible. Seek medical attention immediately.
Cool the burn under cool (not cold) running water for 10-20 minutes. Do not apply ice, butter, or oil. Cover with a sterile, non-stick bandage. Seek medical help for large or deep burns.
The moon rises in the east and sets in the west. If the moon rises before sunset, the illuminated side is West. If it rises after midnight, the illuminated side is East.
Acorns contain tannins which are bitter and toxic. Soak crushed acorns in running water for 24-48 hours, changing the water frequently, until the water runs clear. Then dry and grind into flour.
Find a fallen log or tree. Lean branches against it at a 45-degree angle. Cover with layers of leaves, mud, or bark. Face the opening away from the wind and towards the fire for warmth.
Use chlorine dioxide or iodine tablets according to package instructions. Allow the water to sit for the required time (usually 30 minutes) before drinking. This does not remove heavy metals or chemicals, only biological pathogens.
Animals often move along ridgelines or water sources. Look for sign like droppings or feeding stations. If you see a trail, follow it cautiously. Avoid making noise that mimics prey; move slowly and quietly.
Prepare a tinder bundle of dry, fluffy material (dry grass, bark fibers, bird feathers). It should be the size of a grapefruit. Keep it dry and ready before starting the fire. A good tinder bundle catches a spark easily.
Apply mud or clay to exposed skin to repel biting insects. Avoid sleeping near stagnant water where mosquitoes breed. Shake out shoes and clothing before putting them on to remove hidden spiders or ants.
Look for green vegetation, bird flight patterns, or animal tracks leading downhill. Digging in the bend of a dry riverbed (inner curve) can sometimes yield moist sand. Do not dig near cactus spines; they may contain water but are hard to access safely.
Never eat snow directly; it lowers body temperature and causes dehydration. Melt snow over a fire or in a container before drinking. If no fire, melt snow in your mouth or use body heat in a sealed bag against your skin.
Apply direct pressure with a clean cloth for 5-10 minutes. Do not peek to check if bleeding stopped. If blood soaks through, add more cloth on top. Elevate the wound above the heart if possible.
Stick a pole vertically in the ground. Mark the tip of the shadow. Wait 15 minutes. Mark the new tip. The line between marks runs West to East (first mark is West). Stand with the first mark on your left; North is in front of you.
Never eat wild mushrooms unless identified by an expert. 90% of fatal poisonings come from misidentification. Stick to known safe species like Chanterelles or Morels (cooked) if you are certain. If in doubt, do not eat.
Construct a ridgepole between two supports. Lean smaller branches against it to form a frame. Cover with 2-3 feet of dry leaves, pine needles, or grass. The thick insulation layer traps body heat effectively in cold environments.
Fill clear plastic bottles with clear water and lay them in direct sunlight for 6 hours (or 2 days if cloudy). UV radiation kills pathogens. This method works best for clear water and does not remove chemicals.
Look for broken twigs, flattened grass, and disturbed soil. Fresh tracks will have sharp edges; old tracks are filled with dirt or leaves. Follow the direction of travel by looking for the deepest part of the track (the heel).
The ‘Teepee’ structure is best for starting fires as it allows maximum airflow. Once established, switch to a ‘Log Cabin’ or ‘Lean-to’ structure to sustain the fire for cooking or warmth. Ensure the base is clear of debris to prevent ground fires.
In tropical environments, look for vines with milky sap (often toxic) and plants with thorns near water sources (potential poison). Safe water is often found by digging in dry riverbeds or following animal trails to water. Avoid eating insects with bright colors.
Avoid physical exertion during peak heat (10 AM to 4 PM). Wear loose, light-colored clothing to reflect sunlight. Breathe through the nose to conserve moisture. If stranded, stay in the shade and minimize water loss; do not drink urine or alcohol.
Early signs include shivering, confusion, and slurred speech. As hypothermia progresses, shivering stops, skin turns blue/pale, and the person becomes lethargic. Immediate action: move to shelter, remove wet clothes, insulate the body with dry layers and body heat.
For acute sprains, apply the RICE protocol: Rest (stop using the limb), Ice (15-20 mins every 2 hours), Compression (bandage to reduce swelling), Elevation (raise above heart level). This reduces inflammation and pain effectively.
In the Northern Hemisphere, locate Polaris (the North Star). Find the Big Dipper; the two stars at the end of the ‘bowl’ point directly to Polaris. In the Southern Hemisphere, use the Southern Cross: extend the long axis of the cross 4.5 times to find the South Celestial Pole.
Before consuming a wild plant, perform a test: touch to skin (wait 15 mins), touch to lips (wait 15 mins), touch to tongue (wait 15 mins), chew without swallowing (wait 8 hours), swallow small amount (wait 8 hours). If no reaction occurs, eat more. Never test mushrooms this way.
Boiling water at a rolling boil for 1 minute (3 minutes at altitudes above 6,500 feet) kills bacteria, viruses, and parasites. This is the most reliable method when chemical purification is unavailable.
The bow drill method requires a fireboard (soft wood), a spindle (straight, dry wood), and a handhold. Spinning the spindle rapidly against the fireboard creates friction, generating an ember that must be transferred to a tinder bundle. Success depends on dry materials and consistent, fast rotation.
