Since the recreational pastime of geocaching began five years ago, thousands of "treasures" have been hidden around the world.

The caches are planted by hobbyists with global positioning systems for other GPS owners to find.

Geographic coordinates for the cache locations are posted on Web sites, which include:

More than 2,000 caches are listed in Butler County in the 16001 ZIP code. A few of those include:

Sunkin Garden - Located at Moraine State Park, a map for this cache can be found at the park office.

The Old Stone House - A note on the site for this cache states those finding five stashes along the North Country Trail in Pennsylvania can send away to receive a free patch. Those finding 10 will receive a T-shirt.

The Butler Eagle - A brand new cache rated as easy. No clues available.

The Pennsylvania Book Repository - Near the Buffalo Fire Hall. A Rubbermaid cake container that includes paperback books for adults and children.

Quarter Mile - Like some caches listed on the Internet, this one offers poetry with clues:

The businesses won't let you through,

The railroad tracks, they are taboo.

A stream's become the cache's moat,

It's deep but narrow for a boat.

I think you need another clue,

That bridge could offer you a view!

One way in and one way out,

Can you calculate the route?

Waiting for the Train - Hidden in downtown Mars near the old train station, this cache advises lookers to "check out the train station, train caboose, and other historic stuff." It also contains a word scramble clue that must be solved.

Cool by the Pool - Located near North Boundary Park in Cranberry Township, this cache's contents include Cookie Monster Crayons, tape, a notebook, a Washington Trail pin and a Mr. Trophy Travel Bug.
