Lehigh Valley Live: Historic Bethlehem enlists Lehigh students to aid in underground Moravian settlement survey
A Ground Penetrating Radar is exactly what it sounds like — a device that beams a radar signal into the ground. Of course, it has a purpose for penetrating the earth with said signal: the radar measures and denotes environmental disturbances and electrical properties of materials in the earth. Think a CT scan, but for the ground.
Last month, one such device and a group of Lehigh University students helped Historic Bethlehem Museums & Sites take a big step forward in uncovering an unseen chunk of Moravian history.
