A High-Tech Treasure Huntby Anthony Tibbs

You may know about treasure hunts that took place in the

past, but did you know that treasure hunts exist today?

Many people participate in geocaching, a high-tech treasure-

hunting game. Geo means “Earth” and cache means “hiding

place” or “something that is hidden,” so a geocache is a

treasure that is hidden outside. Geocachers use technology

to locate the treasure. Just follow the steps on these pages

and you can be a geocacher, too!

Latitude is distance north or south of the equator. Latitude lines are horizontal.

Longitude is distance east or west of the Prime Meridian. Longitude lines are vertical.

Latitude and LongitudeThe coordinates of the red dot on the map are 30

degrees north latitude and 90 degrees west longitude.

Step 1: Go OnlineBegin the quest online by registering on the geocaching Web site

and looking for a geocache location near you. Then find its coordinates

on the Web site. Coordinates are a set of numbers that identify a

location on a map or a graph. In geocaching, the coordinates are

the latitude and longitude for the location of the geocache.

Native Americans and French explorers

usually avoided the Badlands because

traveling through it was difficult and

dangerous. Today roads, maps, and

clearly-marked trails make traveling

easier. Tired, thirsty hikers can return to

air-conditioned vehicles with a deeper

appreciation of this marvel of nature.

There are other badlands in the world.

Like Badlands National Park, all

badlands seem like places on another

planet. The South Dakota Badlands are

one of the most famous in the world.

They contain some of the weirdest and

most wonderful rocks around.

Check In What causes rocks in the Badlands to have unusual shapes?

WINDOWS Weathering and erosion formed this window in the Wall at Badlands National Park.

WORMHOLES Some sandstone rocks sport pencil-thin holes called wormholes. Most geologists think the holes were left by ancient roots, not worms.

POPCORN When some clay-rich rocks get soaked, they dry into a bumpy, sticky surface called popcorn.

ARMORED MUD BALLS Flowing water rolls a piece of sticky clay mud into a ball. The mud ball rolls down a gully, picking up sand and pebbles. The pebbles form a layer of “armor” around the mud ball.

Boo! It’s a hoodoo. The top layer of rock is more resistant than the layers under it. The harder rock forms a “cap.” The cap protects underlying rock from erosion.

Hiking through the Badlands can be like going on a scavenger hunt. What other outlandish land features might visitors discover here?
