Dig a one-night snow trench
A trench is faster than a quinzhee and warmer than a tarp when you have snow but no time.
1. Find snow at least chest-deep. Test-probe with a stick for hidden rocks and roots.
2. Dig a body-length trench slightly wider than your shoulders and knee-deep below the trench floor.
3. Roof it with skis, poles, or sturdy branches laid across the top, then blocks of cut snow.
4. Leave a small vent hole for CO₂ and mark it from outside with a ski or stick.
5. Line the floor with a pad or thick bough bed before you get in.
Warning: Never seal a snow shelter completely — suffocation is a real risk without a vent.

Navigation

Read a topo map in one minute
Contour lines tell you shape and steepness — the whole map is in the spacing.
1. Close-spaced lines = steep. Wide-spaced = gentle.
2. V's pointing uphill = drainage or creek. V's pointing downhill = ridgeline.
3. Circles inside circles = a summit; hachured circles = a depression.
4. Blue = water, green = vegetation, white = open/rock/snow, brown = elevation.
5. Check the contour interval in the legend before guessing elevation.

Ice & Cold
5 min
Tell if ice is safe to cross
Color, thickness, and history — check all three before you step out.
1. Clear blue or black ice is the strongest. White or opaque ice is half as strong. Grey ice is unsafe — leave it alone.
2. Thickness rules of thumb on clear ice: 4 in / 10 cm to walk, 5-7 in / 12-18 cm for a snowmobile, 12+ in / 30+ cm for a light truck.
3. Drill or chop test holes every 50 ft on unknown ice and measure — don't guess.
4. Skip inlets, outlets, springs, currents, and any area with cracks radiating from a point.
5. Avoid ice near docks and pilings; dark objects absorb heat and thin the ice around them.
Warning: No ice is guaranteed safe. If you break through, kick horizontally, get your arms flat on solid ice, and roll — don't try to climb.

Prevent frostbite on hands
Once your fingers stop hurting in the cold, you have about 20 minutes.
1. Layer: thin liner glove for dexterity, insulated shell for warmth. Never take both off at once.
2. Keep hands moving. Fists, windmilling arms, wiggle fingers inside the glove.
3. Never handle cold metal or fuel with bare skin below freezing — contact frostbite is instant.
4. If fingers go numb, warm them under armpits or against a companion's stomach until sensation returns.
5. Add a hat — vasoconstriction to the hands worsens fast when the head is cold.
Warning: Do not rub frozen tissue with snow or hold near a fire. Warm slowly with body heat or 100-105 °F water.

Build a signal fire that gets seen
The point of a signal fire is smoke and contrast, not warmth.
1. Pick a spot with a wide sky view — a ridge, clearing, or lakeshore. Not under trees.
2. Build three fires in a triangle 25 m apart if you have the fuel; three of anything is a distress signal.
3. Keep a pile of green boughs, wet moss, or damp grass at each fire, ready to dump on.
4. Against snow use dark smoke: green vegetation. Against dark forest use white smoke: damp grass, moss.
5. Only light when you actually hear or see a search — smoke ignored is smoke wasted.

Ground-to-air signals every pilot knows
Five internationally recognized symbols. Make each one 10 ft / 3 m tall in high-contrast material.
1. V = require assistance.
2. X = require medical assistance.
3. N = no or negative.
4. Y = yes or affirmative.
5. → (arrow) = proceeding in this direction.
6. Stomp them into snow, dig them into sand, or lay them out in dark logs on light ground.
Tip: Size and contrast matter more than shape. From 2,000 ft, small is invisible.

Harvest and use birch bark tinder
Paper birch bark contains oils that light in rain and snow — one of the most reliable natural tinders in the northern woods.
1. Take only loose, curling outer bark from live trees or strip freely from downed birch — never cut the inner bark of a healthy tree.
2. Shred a small handful into thin ribbons and tease the edges until they look like feathers.
3. Build a small platform of dry twigs, then set the shredded bark on top so air can flow underneath.
4. Light from below with a match, spark, or ember; the oils will sustain flame for 30–60 seconds.
5. Feed pencil-thick kindling the moment flames catch, and add heavier wood only when the fire stands on its own.
Warning: Girdling a live birch — cutting a full ring of bark around the trunk — will kill the tree. Take only loose outer layers.
Water
20 min
Melt snow and ice for drinking water
Snow is 90% air. Melting it wrong wastes fuel, scorches your pot, and can trigger cold injuries.
1. Start with a small amount of liquid water in the pot — even a couple of ounces — before adding snow.
2. Add snow gradually, stirring so the ice contacts water rather than dry pot metal.
3. Prefer ice or hard, dense snow over fresh powder — you get four times more water per volume.
4. Bring to a rolling boil for 1 minute (3 minutes above 6,500 ft) before drinking to kill pathogens from animal fecal contamination.
5. Insulate the pot and store extra water in bottles kept close to your body so it doesn't refreeze.
Warning: Never eat snow directly for hydration — it drops your core temperature and burns calories your body cannot afford to lose.
Ice & Cold
15 min
Insulate under your body, not just over
The ground pulls heat out of you faster than cold air. Two-thirds of your insulation should be underneath.
1. Never sleep directly on cold ground, snow, or bare rock — you will lose heat you cannot replace.
2. Build a raised bed of dry debris at least a hand-span thick — dry conifer boughs, dead leaves, or grass — and compress it slightly under your weight.
3. Add a second layer of finer, softer material on top for comfort.
4. If you have a foam pad, keep it as your closest layer to the ground; put a sleeping bag or emergency blanket on top of the pad, not under it.
5. Rebuild loft each night — compressed debris insulates far less than fresh, lofted debris.
Tip: Test the bed by lying on it for 5 minutes before dark. If your back feels cold, add another 4 inches of debris before you commit to sleeping.
Signaling
5 min
Signal SOS with light, sound, or ground marks
SOS is the most universally recognized distress signal — three short, three long, three short — with any signaling method.
1. Light or sound: three short bursts, three long bursts, three short bursts, pause, repeat.
2. With a whistle: three quick chirps, three 2-second blasts, three quick chirps.
3. With a flashlight or mirror: three short flashes, three long flashes, three short flashes toward the observer.
4. On the ground: stamp or scrape 'SOS' in letters at least 10 feet tall in snow, sand, or a clearing.
5. Keep repeating in cycles with a pause between; a single SOS is easy to miss.
Tip: The pattern matters more than the medium. A rescuer who hears three-three-three anything will investigate.

Choose high-contrast colors for signal panels
Contrast beats color. What matters is that your signal looks nothing like the ground around it.
1. In snow or on light rock: use dark materials — a garbage bag, dark jacket, or scorched wood.
2. In green forest or grass: use bright orange, yellow, or blaze pink if you have them; a silver space blanket also works.
3. On dark ground or wet dirt: light or reflective materials — foil, mirrors, or white cloth.
4. Weight the corners and edges with rocks so the panel doesn't blow away.
5. Combine ground panels with a geometric shape — a big X or triangle — so aircraft recognize it as human-made.
Tip: Bright red is the color humans notice fastest in natural settings. If you have a red jacket, keep it on top when signaling.
First Aid

Manage a sprained ankle in the backcountry
A sprained ankle can strand you if handled wrong. Support early and you can often walk out on it.
1. Sit, elevate, and cool the ankle for 15–20 minutes with cold water, snow, or a wet bandana — this reduces swelling that will otherwise lock the joint.
2. Assess: if you can bear weight cautiously without a grinding sensation or extreme pain, it's likely a sprain rather than a fracture.
3. Support with a figure-8 wrap: run cloth or an elastic bandage under the arch, across the top of the foot, around the back of the ankle, and back across in an X pattern.
4. Re-lace the boot firmly enough to stabilize the ankle but not tight enough to cut circulation. Check toes for warm color regularly.
5. Walk out slowly using a trekking pole or stout stick on the injured side. Rest and re-cool at every break.
Warning: Numbness, severe deformity, inability to bear any weight, or grinding sounds mean a possible fracture. Splint in place and get help rather than walking on it.
Shelter
15 min
Anchor a tarp or tent for a storm
Standard stakes fail in wind and wet ground. Storm anchors keep your shelter down when weather turns.
1. Replace stakes with deadman anchors — bury a stick, rock, or stuff sack full of gravel horizontally with the guyline tied around it.
2. In snow, dig a T-slot: cut a channel across the guy direction, lay a stake or stuff sack horizontally, and pack snow over it.
3. Add secondary guylines from mid-panel tie-outs on every wall — not just corners.
4. Angle guylines at 45° from the tarp to the anchor for the strongest pull-through-shear geometry.
5. Re-tension every 2–4 hours during a long storm as ground softens and cords stretch when wet.
Tip: Cut short (4-inch) toggles from sticks and larks-head your cord around them — they hold better than tied loops when guys need to be adjusted repeatedly.
Shelter

Dig a snow cave
A snow cave traps body heat and blocks wind, turning a deadly storm into a survivable night.
1. Find deep, stable snow on a lee slope or drift — not avalanche terrain.
2. Dig an entrance tunnel lower than the sleeping platform so cold air sinks away from you.
3. Hollow out a domed chamber large enough to lie in; keep the roof at least 1 foot thick.
4. Poke a vent hole through the roof with a stick to prevent CO₂ buildup.
5. Line the floor with pads, packs, or boughs and mark the entrance from outside with a ski or branch.
Warning: Never seal a snow cave airtight. Suffocation from exhaled CO₂ is a real risk without ventilation.

Build a night signal fire
At night, flame and light contrast matter more than smoke. A signal fire needs to be seen from the air.
1. Choose a high, open spot with a clear view of the sky — ridge, clearing, or shoreline.
2. Build three small fires in a triangle 25 meters apart if you have the fuel and it's safe.
3. Keep a large supply of dry, fast-burning material ready to throw on when you hear an aircraft.
4. Use bright flames against dark terrain; against snow, dark smoke from green boughs contrasts better.
5. Only light when you have reason to believe searchers are nearby — a fire left burning is a fire that can escape.
Warning: Never build signal fires in dry, windy conditions where embers can ignite surrounding forest. Clear the ground to mineral soil first.

Build a Log Platform for Campfires on Deep Snow
Prevent your campfire from sinking into deep snow by constructing a sturdy, green-wood log platform. This technique ensures a stable burn.
1. Select 4-6 fresh, green logs, 4-6 inches in diameter and 4-6 feet long.
2. Clear a level, firm area of snow, roughly 4x4 feet, for your fire platform.
3. Lay down two parallel logs as your base, spaced about 2-3 feet apart.
4. Place the remaining logs perpendicularly across the base logs, close together, forming a solid raft.
5. Cut and place smaller, green branches around the edges of your platform to contain coals and ash.
6. Cover the log platform with a thin layer of mineral soil or rocks, if available, before lighting your fire.
Tip: Gather more green logs than you think you'll need; they can be used for reinforcement or to extend the life of your platform later.
Warning: Never use deadfall that is punky or rotten, as it will burn through quickly.
