GPS devices help modern-day explorers locate hidden treasures

Geocaching brings treasure hunting to the 21st century.

REMEMBER that game where you tried to find a hidden object while the other kids yelled, "You're getting warmer" or "Now you're cold, ice cold"?

Twenty-first-century game players can now call on space satellites and atomic clocks to give them the same sorts of clues.

This modern version is called geocaching; it's played with hand-held global positioning system receivers. And it's way more fun than the birthday-party game.

"I found it! It's right over here," yelled Julie Martin of Fredericksburg, bounding excitedly through the leaf mold on the forest floor last Friday.

It was the third find of the day for Martin and her boyfriend and geocaching partner, J.R. Grey, also of Fredericksburg. But it was the first one that Martin had spotted.

The white Tupperware box was nestled at the base of a huge beech tree, about 50 yards off the nature trail in Northern Virginia's Fountainhead Regional Park. Partially shielded from view by carefully placed bark, sticks and leaves, the box required a sharp eye to spot.

Opened, it revealed a stuffed bichon frisé that made rude noises when squeezed, a movie video, a sci-fi paperback, a deck of playing cards, a Matchbook helicopter, a Beatles compact disc and assorted other questionable treasures.

It's the lure of the hunt that's addictive, not the loot at the end of the trail.

It works this way: Cache hiders pick a nice outdoor spot that's fairly easy to get to, but not all that obvious. They then post the latitude and longitude of their caches on an Internet site (www.geocaching.com), with directions to the trailhead and a couple of general clues to get the hunt started.

Those who have already found the cache usually post that fact at the bottom of the directions page with comments about how much fun they had doing it.

Cache seekers go to the Web page for a directory of nearby caches. Once they select one, they enter the latitude and longitude numbers in their GPS units and drive or walk to the starting point. Then they wander over hill and dale, through wood and swamp, guided by the little black arrow on the GPS screen.
