Kris Lockyear, of  Phys.org, has written an informative article about alternative methods archaeologists use to see underground other than excavation, as seen during the recent discoveries near Stonehenge at Durrington Walls. Stonehenge and Durrington Walls are part of the UNESCO World Heritage site Stonehenge, Avebury and Associated Sites.

"One suite of techniques available to archaeologists is geophysical survey (or "geofizz" to fans of the TV show Time Team). Of the many geophysical techniques that exist, archaeologists generally make use of four: magnetic gradiometry, earth resistance, ground penetrating radar (GPR) and magnetic susceptibility. Each technique measures some aspect of the ground below the surface. By taking many readings on a regular grid and plotting the results, information about the archaeological site can be gained without having to dig it up."
