BATTLE GROUND, Ind. (AP) - Tippecanoe County officials want to create a computer-assisted map of a historic battlefield that could yield clues about archaeological remnants buried there.

The Tippecanoe County Historical Association plans to use a device to measure anomalies in the earth's magnetic field to find underground objects. It also might use ground-penetrating radar to find items if funding can be found.

Archaeologist Colby Bartlett says it would be the first professional investigation of the site.
