Celestial Navigation
... Wayfinding is the navigation in open seas without any assistant of navigational instrument of any form. The wayfinders merely observe the stars overhead, the sun, the swells of the ocean and other signs of nature for clues to direction and location. This method is used for voyaging for over 1000s of ...
