Archaeologists and PBS crew use geophysics and LIDAR

At an archaeological site at Crow Canyon, near Cortez, Colorado, a team of archaeologists, supported by a PBS film crew, were using ground penetrating radar, magnetometry, and resistivity geophysical methods to try to image the subsurface of the Basketmaker III community. They also used airborne LIDAR to map out structure locations, drainage and irrigation features and even old paths. [Source: The Cortez Journal. Image: Cortez Journal]
