There are about 150,000 of them spread throughout 213 countries and you need satellites to help you find them. What are they? They're geocaches and geocaching is a sport that is quickly gaining popularity.The geocaches come in all different sizes and shapes. Usually stored in a waterproof container, these caches are treasures of minimal value. The container is often a Tupperware container or ammo box. The "treasures" can be just about anything you can imagine: a mini-stapler; a toy soldier; foreign coins. How do you find them? That's satellite part. If you haven't been in a cave for last five years, you've probably heard of Global Positioning System, or GPS. Just in case you're one of cave people, GPS is a system of 24 satellites orbiting earth at an altitude of 11,000 miles. A small handheld receiver, a little larger than a cell phone, picks up signals from satellites and can pinpoint your position anywhere on earth, sometimes as accurately as 3 meters. If you go to Geocaching.com you can enter your location by ZIP Code, state, or country and get a list of caches in your area. Each listing has a log of who found cache, when it was found, and usually what trinkets were taken and left. You are given coordinates of cache in degrees of longitude and latitude. Enter those numbers in your GPS and start following that little handheld device. It may sound easy, but depending on individual cache, it can be a challenge.
