Each method employs a different type of science to “see” underground. Magnetometry measures and maps patterns of magnetism in the soil. Activities such as burning leave magnetic traces in the soil and leave behind an outline for researchers. Resistivity studies utilize electrical currents passed through the ground to measure resistance, which usually indicates underground structures. Ground penetrating radar uses radar pulses to produce images of the subsurface.

The most advanced technique used at Crow Canyon has been LiDar, light detection and ranging, which maps features utilizing light waves bounced off the ground from a high altitude, in this case, an airplane. The Time Team America crew completed a LiDar study of 300 acres surrounding the Dillard site last month, creating a three-dimensional map of the area.

Diederichs said the results of the study were phenomenal and the significance cannot be minimized. “It was the coolest thing,” she said. “The map pulls out structures and all the drainages and features on the landscape. You see the travel paths that were used and even the smallest features. It is amazing.”
