How to navigate using nature

Watch more with these video collections:

In a world increasingly tethered to digital information, where GPS and smartphones are commonplace, it’s easy to forget that humans and animals have relied on Mother Nature’s navigational cues for thousands of years.

But what if there’s no phone signal or the phone runs out of battery? Would we get lost without modern conveniences?

What if we want to understand the clues and cues that nature provides? Can we navigate using nature?

The art of wayfinding is an ancient skill we can still learn to use. In this BBC Earth Kids wayfinding video, Fran Scott shares how to determine the four cardinal directionsβ€”north (N), east (E), south (S), west (W)β€”using the sun, shadows, sticks, stars, trees, and moss.

The shadow stick method can create a makeshift compass rose by marking shadow points as the sun moves across the sky. If you don’t have more than one stick, you can use rocks or other markers to note the points.

On a clear night in the northern hemisphere, finding Polaris, also known as the North Star, can help you find true north. Locate the Big Dipper (Ursa Major). The two stars at the end of its cup point to Polaris, the tip of the Little Dipper’s (Ursa Minor) handle. From NASA:

“Polaris is located quite close to the point in the sky where the north rotational axis points – a spot called the north celestial pole. As our planet rotates through the night, the stars around the pole appear to rotate around the sky. Over the hours, these stars each sweep out a circle around the celestial pole. The farther a star is from the pole, the larger the circle it travels around the sky. Some stars travel a great distance over the course of the night.

“Polaris is different. Because it’s so close to the celestial pole, it traces out a very small circle over 24 hours. So Polaris always stays in roughly the same place in the sky, and therefore it’s a reliable way to find the direction of north.”

On a clear night in the southern hemisphere, finding the Southern Cross or Crux and the two pointers (Alpha Centauri and Beta Centauri) can determine due south. This Lotsafreshair video demonstrates in less than a minute:


Fran Scott also demonstrates how deciduous trees can help wayfinders find their way. In the northern hemisphere, trees grow branches toward the sunlight in the southern sky; in the Southern Hemisphere, the trees grow toward the sun in the north.

Alternatively, moss prefers the cooler side of a tree; if you find deciduous treesβ€”or other vertical smooth surfaces that aren’t close to the groundβ€”with moss on only one side, that side may face north in the northern hemisphere and south in the southern hemisphere.

Important note: Because moss will grow anywhere moist and shady, check multiple trees for this pattern.
