Here’s a longer article from the NY Times last weekend about the “wave pilots” of the Marshall Islands. In this traditional form of navigation, the pilots don’t use maps or celestial navigation, but instead read and (literally) feel the waves and navigate based on the refraction/reaction of the water.

Highly recommend–there’s brain science, astrophysics, seasickness, and more: The Secrets of the Wave Pilots.


(If you want to read more about the “stick charts” the article briefly mentions, here’s an older article from The Smithsonian with pictures, and here’s a more technical explanation from a Marshallese publication.)
