How Do Geocachers Use Coordinates to Find Hidden Treasure?
Imagine a treasure hunt where the treasure is hidden somewhere in the real world. It is called geocaching, and people play it all over the globe.
More fun facts
- Geocachers use GPS devices to find hidden containers called geocaches.
- There are millions of geocaches around the world, in cities, forests, deserts, on mountaintops and even underwater.
- When you find a geocache, you sign the log inside, hide it back where you found it, and log your visit online.
- Some caches are virtual, so you visit a spot instead of finding a container.
- EarthCaches lead you to places where you can learn how geology shaped the land.
- One degree of latitude is about 69 miles, and one second of latitude is only about 101 feet.
