Living Off The Grid: Nature’s Compass - Finding Your Way Using Nature
Long before the compass was created by humans, people used nature to find their way around the lands and across the waters. Sailors still use a special instrument called a sextant to navigate the seas. The sextant is designed to measure the angle of the stars above the horizon to find accurate direction and position in terms of the latitude and longitude. Before the sextant was used, Vikings used Sun Stones similar to a sundial that helped them maintain a proper course.
