In the Northern Hemisphere: The sun is always in the southern sky. At noon, shadows point north.

Shadow Stick Method

EasyDaytime with visible sun

90%

reliability

1

Find a straight stick ~3ft long and push it into flat, level ground

2

Mark the tip of the shadow with a rock or peg (Mark 1)

3

Wait 15-20 minutes

4

Mark the new shadow tip position (Mark 2)

5

Draw a line from Mark 1 to Mark 2 — this line runs roughly West to East

6

Mark 1 is West, Mark 2 is East. Stand with your left foot on Mark 1 — you face North. South is behind you.

7

First shadow (before noon) points west-ish, shortest shadow at noon points to your celestial pole

North Star (Polaris)

EasyClear night, Northern Hemisphere only

95%

reliability

1

This method works ONLY in the Northern Hemisphere

2

Locate the Big Dipper (Ursa Major) — 7 bright stars forming a ladle

3

Find the two stars at the end of the "bowl" (pointer stars: Merak and Dubhe)

4

Follow the line from these pointer stars upward ~5x the distance between them

5

This leads to Polaris (North Star) — the last star in the Little Dipper handle

6

Polaris is always within 1° of true north

7

Your latitude = Polaris altitude angle above horizon

Southern Cross (Crux)

MediumClear night, Southern Hemisphere

85%

reliability

1

This method works in the Southern Hemisphere

2

Locate the Southern Cross — 4 bright stars forming a cross, plus a 5th fainter star

3

Be careful not to confuse with the False Cross (larger, dimmer)

4

Follow the long axis of the cross downward ~4.5× its length

5

This point is roughly the South Celestial Pole

6

Drop a line straight down to the horizon — that is South

7

For better accuracy: draw a line between the two Pointer stars (Alpha and Beta Centauri), bisect it with the Southern Cross long axis

Watch Method (Analog)

EasyDaytime with visible sun and analog watch

75%

reliability

1

Hold the watch horizontal. Point the HOUR HAND at the sun

2

Bisect the angle between the hour hand and the 12 o'clock mark

3

The bisecting line points SOUTH

4

If using daylight saving time, use the 1 o'clock mark instead of 12

5

Current time: 12:00 — hour hand at 12 position

6

For best results, use around midday. Accuracy decreases near dawn/dusk

Moss Growth Direction

EasyAnytime in forested areas (LEAST reliable)

40%

reliability

1

⚠️ This is the LEAST reliable method — use only as a last resort

2

In the Northern Hemisphere, moss TENDS to grow on the North side of trees

3

This is because that side receives less direct sunlight and stays damper

4

However, moss grows where conditions are right — it does NOT always follow this rule

5

Check MULTIPLE trees and rocks for consistency before relying on this

6

Look for other indicators: tree rings may be wider on the sun-facing side

7

Never rely on moss alone — always cross-reference with other methods

Moon Navigation

MediumNight with visible moon

70%

reliability

1

If the moon rises BEFORE midnight, the illuminated side faces West

2

If the moon rises AFTER midnight, the illuminated side faces East

3

A crescent moon: draw a line from tip to tip through the center, continue to horizon

4

For a crescent moon before midnight, that point on the horizon is roughly South

5

Full moon: navigates similarly to the sun (opposite path)

6

The moon is roughly in the south at its highest point
